Notice to Authors
1. General Information
ChemCatChem is a journal of chemical catalysis, founded by the Real Sociedad Española di Química (Royal Spanish Chemical Society) and the Gesellschaft Deutscher Chemiker (German Chemical Society, GDCh) and published by Wiley-VCH. Contributions to ChemCatChem cover research in all fields of catalysis, including heterogeneous, homogeneous, bio- and nanocatalysis. ChemCatChem is published monthly and contains Communications, Full Papers, Reviews, Minireviews, Highlights, Concepts, Book Reviews, and Conference Reports. Articles other than original research papers, (i.e., Communications and Full Papers) are generally written upon invitation. Unsolicited manuscripts, however, are welcome for consideration, as long as they fit into the scope of the journal. Correspondence, Essays, and contributions reviewing Web Sites or Databases are also occasionally featured.
ChemCatChem does not publish manuscripts that have already appeared in other media, either in print or electronically. The authors must inform the Editor of manuscripts submitted, soon to be submitted, or in press at other journals that have a bearing on the manuscript being submitted to ChemCatChem.
The Ethical Guidelines for Publication in Journals and Reviews issued by the European Association of Chemical and Molecular Sciences are followed and applied by the Editors of ChemCatChem. In particular, authors should reveal all sources of funding for the work presented in the manuscript and should declare any conflict of interest.
With the exception of Book Reviews, Conference Reports, Web Sites, and Databases, all manuscripts that are suitable for consideration will be peer-reviewed and, if accepted for publication, edited with a view to clarity, brevity, and consistency.
The journal ChemCatChem is fully electronic, however hardcopies of ChemCatChem are available through print on demand. All color figures in published articles are free of any charges. Authors are encouraged to submit high-resolution color graphics.
2. Initial Manuscript Submission
We request that you submit your manuscript by using our online submission service, Editorial Manager, which can also be accessed through our homepage (www.chemcatchem.org). Authors submitting a manuscript to ChemCatChem for the first time are asked to characterize their main research interests with a maximum of five keywords from the Keyword List for Authors and Reviewers. If you encounter any problems, please contact the editorial office.
For the initial submission of a manuscript please prepare a single file (allowed formats: Word, RTF, Postscript, PDF) with all schemes, figures, and tables integrated into the text. Please make use of our templates to prepare your submission. Include the Supporting Information (if applicable) at the end of the document.
The cover letter is vital and should include a short text justifying why your article should appear in ChemCatChem. Authors are encouraged to provide the names and contact details of suitable referees. The editor must be informed of any conflict of interest. Please avoid formatted text in your cover letter.
If the manuscript is a revised/extended version of a manuscript previously rejected by ChemCatChem, the author must inform the editor about the previous submission in the cover letter and explain in detail which changes have been made. Similarly, if the manuscript was previously submitted to any other of ChemCatChem′s sister journals (Angewandte Chemie, Chemistry–A European Journal, Chemistry–An Asian Journal, ChemBioChem, ChemPhysChem, ChemMedChem, ChemSusChem, ChemElectroChem), then please state the manuscript number of the previous submission in the cover letter and outline, in detail, the changes and revisions that have been made. This will help in the review process.
Contributions must be of top quality and make an outstanding contribution to the development of catalysis research. Those that are do not represent a sufficient advance in catalysis or are too specialized for the general readership of ChemCatChem will be returned to the authors without further external review (ca. 25%). The quality of contributions is usually assessed by two or more independent referees. Detailed information that could be of importance to the referees, but that is unlikely to be of interest to the reader can be submitted as an enclosure or clearly marked as Supporting Information. Only articles that have already been published in a scientific journal should be cited. The citation should be fair and informative but not excessive. Copies of cited publications not yet available publicly should be submitted along with the manuscript. Unpublished results and lectures should only be cited in exceptional circumstances.
If authors have to or want to make their publications freely available at the moment they are published (open access), ChemCatChem offers such a service. Under the keyword OnlineOpen you can find all the information about this subject on our homepage. ChemCatChem also complies with requests or mandates from research funding agencies, for example, the US National Institutes of Health (NIH), to make manuscripts freely available online in unedited form after acceptance. In general we recommend that authors link on their homepage to their ChemCatChem publication through the "Digital Object Identifier" (DOI). Only in this way can CrossRef function correctly and full-text downloads be tallied.
If your manuscript is accepted, you will be provided with detailed instructions on how to prepare files suitable for high-quality typesetting and production.
Authors are asked to make their manuscripts suitable for a heterogeneous readership and to be considerate to our many readers for whom English is a foreign language—please use a simple, clear style, and avoid jargon. It would be helpful to the referees and editors if manuscripts were checked by a native English speaker prior to submission. Please inform us in the cover letter if your manuscript has been professionally edited before submission, such as by Wiley English Language Editing Services.
3. Types of Contribution
Reviews deal with topics of current interest in any of the areas covered by ChemCatChem. Rather than an assemblage of detailed information with a complete literature survey, a critically selected treatment and discussion of the material is desired. Unsolved problems and possible developments should also be discussed. A Review should consist of a maximum of 40 pages (approximately 65000 characters) of main text, footnotes, literature citations, tables, and legends. Reviews should be divided into numbered sections. Cross-references in the text refer to these section numbers. The review starts with an Abstract (800–1200 characters, no references). This text should not be a mere summary; rather, it should arouse the readers′ interest. The Introduction should introduce the non-specialist to the subject as clearly as possible. A Review should conclude with a Summary and Outlook section, in which the achievements and new challenges for the subject are presented succinctly. In addition, a biographical sketch (500–700 characters) and a portrait-quality photograph of each author, as well as a graphical suggestion for a rectangular picture (frontispiece: 18.0 cm wide×19.5 cm high) to face the first page, should be submitted.
A Minireview should present current topics in a concise review style. The content should balance scope with depth, and references to important works from others that are significant to the topic, should be included. As a Minireview is much more focused than a Review, it is shorter (15 pages of text, approximately 25000 characters) and does not contain a frontispiece or biographical sketch(es). It should still include an Abstract (no references).
In the Highlights section, very important new results of original research are described, in general by a third person, with a view to highlighting their significance. The results should be presented clearly, but as succinctly as possible, without the comprehensive details required for an original article. Highlights may be organized as the author wishes, but should not be more than three pages (approximately 8500 characters) in length. Chemical formulae, figures, and schemes should be restricted to important examples, and the number of references kept to a minimum.
Concepts are short articles which emphasize the general concepts that have guided important developments in a specific area and their implications for future research. The reference section should only include the key papers that have contributed to conceptual advances in the field under review, rather than being fully comprehensive. The author should aim to provide the non-specialist reader with a useful guide and the expert with a new angle on a familiar problem. Concept articles may be organized as the author wishes, but should include a short Abstract (approximately 600–1000 characters, no references) that succinctly describes the concepts under discussion. Articles should consist of around 10 pages of text (approximately 17000 characters) including references, tables, and legends. The liberal use of schemes, figures, and color is encouraged.
3.5. Communications and Full Papers
Communications and Full Papers present results of experimental or theoretical studies of general interest or great importance to the development of catalysis research.
Communications: Inclusive of all references, footnotes, and tables, a Communication should be no longer than approximately 10000 characters. Chemical formulae, figures, and schemes may also be added. Longer Communications will be accepted only if their quality warrants special consideration, and a written justification of their length is provided. Communications should not be divided into sections. However, experimental details can be summarized separately under the heading Computational Methods or Experimental Section. The first paragraph of a Communication should give an introduction to enable readers unfamiliar with the subject to become acquainted with the importance of the results presented. In the final paragraph the results should be summarized succinctly, and one sentence should be devoted to their significance and, if appropriate, to remaining challenges. For better expression in abstracting services, Communications will henceforth include an Abstract (600–1000 characters, no references).
Full Papers: Full Papers have no specific length restrictions; however, the Editorial Office requests that space be used thoughtfully and economically. Full Papers contain an Abstract, which should be brief (600–1000 characters, no references) and not too technical, and an Introduction including relevant references. The presentation of Results and Discussion may be combined or kept separate. These sections may be further divided by subheadings. The Experimental Section or Computational Methods should be placed just before the reference section. ChemCatChem will not publish Full Papers that consist mainly of results reported in previous Communications with an added experimental section.
3.6. Book Reviews
Reviews of books are written on invitation. Suggestions for books to be reviewed and for reviewers are welcome. Publishers should send brochures or, preferably, the books directly to the Editorial Office. Unsolicited books will not be returned.
3.7. Conference Reports, Essays, Correspondence, etc.
Reports on recent events and comments on publications in ChemCatChem or on topics of high current interest are welcome if they contribute to the scientific discussion in the area of catalysis.
4. Guidelines for the Preparation of Manuscripts
Your manuscript can be processed more rapidly if it is arranged as described below. Unless stated otherwise, the following instructions apply to all categories of contributions.
4.1. Title Page
In order: title; authors′ names with academic titles, alphabetical footnotes ([a],[b],....) referring to addresses, and an asterisk to denote the correspondence author; footnotes containing affiliations of all authors including the full postal address, fax number, and e-mail address of the correspondence author; series title, number, and dedication, if applicable.
4.2. Results and Discussion
This section may be combined or kept separate and may be further divided by subheadings. It should not be cluttered with technical details.
4.3. Computational Methods/Experimental Section
(Full Papers and Communications only.) This section should be given in sufficient detail to enable others to repeat your work. In so far as is practical, authors should use a systematic name for each title compound in the Experimental Section (as suggested by IUPAC or Chemical Abstracts). Please do not use computer programs to generate elaborate systematic names or use extremely long compound names. For the sake of clarity, general descriptors such as compound 1, dendrimer 2, or alcohol 3 should be used.
Equipment and conditions used for the measurement of physical data, as well as any organisms, proteins, or nucleic acids used should be described at the beginning of the Experimental Section. Quantities of reactants, solvents, etc. should be included in parentheses rather than in the running text (e.g., "Triphenylstannyl chloride (0.964 g, 2.5 mmol) in toluene (20 mL)..."). Physical data (in SI units whenever possible) should be quoted with decimal points and negative exponents (e.g., 25.8 JK−1mol−1). The purity of all new compounds should be verified by elemental analysis, to an accuracy of within ±0.4%.
Detailed presentation of physical data: Rf=0.38 (CHCl3/MeOH 9:1); m.p. 20 C; [α]D20=−13.5 (c=0.2 in acetone); 1H NMR (200 MHz, [D8]THF, 25°C, TMS): δ=1.3 (q, 3J(H,H)=8 Hz, 2H; CH2), 0.9 ppm (t, 3J(H,H)=8 Hz, 3H; CH3); IR (Nujol): \tilde \nu =1790 cm−1 (C[dbond ]O); UV/Vis (n-hexane): λmax (ε)=320 (5000), 270 nm (12000 mol−1dm3cm−1); MS (70 eV, EI): m/z (%): 108 (20) [M+−H], 91 (100) [C7H7+]; elemental analysis: calcd (%) for C12H11AsOS (278.2): C 51.85, H 3.99, As 26.93, S 11.53; found: C 51.59, H 3.96, As 27.07, S 11.39.
4.4. Acknowledgements 4.5. References
In the text, numbers corresponding to the appropriate reference should be typed in square brackets as superscripts and after any punctuation, where applicable (e.g., Blobel). References must be listed in order of their appearance in the text. Please do not format the references section with the "Numbering" function on your word-processing program. If you use the automatic reference collation system of your word-processing program (Footnotes, EndNote), please convert the references into normal, typed text before submission of the final manuscript, otherwise they may disappear when typeset. Journal titles should be abbreviated according to the Chemical Abstracts Service Source Index (CASSI). Unpublished results and lectures should only be cited for exceptional reasons. Please follow the examples below.

The page range is optional but its presence or absence should be consistent throughout any given manuscript. If there are less than 10 authors, the names of all authors should be provided (et al. should not be used). If there are 10 authors or more, only the name of the first author in the list should be given, the remaining names should be replaced by "et al.", the journal name, volume, and page details should be followed by "see Supporting Information", and the complete reference should be provided in the Supporting Information.
Illustrations (structural formulae, figures, schemes) should, if possible, be designed for reduction to a one-column format (8.4 cm wide). The maximum width is the two-column format (17.5 cm wide). For optimum reproduction, illustrations should be larger than the desired final size. We recommend: Helvetica font or Arial for script; size of lettering 3–3.5 mm; total maximum width 14 cm (or 28 cm for two-column width) for 60% reduction. Please use only one size of writing in any one diagram. For high-quality reproduction, high-resolution graphics must be supplied. Mathematical formulae should not be incorporated into the text as graphic files. Please type mathematical formulae as normal text in the body of the text as far as is possible.
Computer-aided image enhancement is often unavoidable. However, such manipulation may not result in data that are less relevant or unrepresentative being shown and/or genuine and significant signals being lost. A clear relationship must remain between the original data and the electronic images that result from those data. If an image has been electronically modified, the form of the modification must be given in the Figure caption. If computer-aided processing or modification of an image is a fundamental part of the experimental work, then the form that this processing takes must be clearly described in the Experimental Section.
Please italicize symbols of physical quantities in both graphics and the text, but not their units (e.g., T for temperature, in contrast to T for the unit Tesla; J, but Hz; a, but nm). Stereochemical information (cis, Z, R, etc.), locants (N-methyl, α-amino), and symmetry designations (C2v) should also be italicized. Chemical formulae should be numbered with boldface Arabic numerals (e.g., 1). Labels of axes should be separated from their units by a slash (e.g., T/K). Abbreviations such as Me, Et, nBu, iPr, sBu, tBu, and Ph (not [phiv ]) may be used. General substituents should be indicated by R1, R2 (not R2, which means 2R), or R, R′. The spatial arrangement of the substituents should be indicated by hatched lines or a wedge. A minus sign must be as long as the crossbar of a plus sign.
Each figure and scheme should have a legend. These should be typed as text of the manuscript, rather than form part of a graphic.
Tables must have a brief title and should only be subdivided by three horizontal lines (head rule, neck rule, foot rule). Footnotes in tables are denoted [a],[b],[c], etc. Tables should not be created as graphics files or contain line breaks within single cells.
4.9. Table of Contents
For all types of contribution, a short text for the Table of Contents (TOC) should be included. This text should be about five lines (approximately 300 characters) in length and formulated to arouse curiosity. Repetition or paraphrasing of the title and presentation of experimental details should be avoided. The use of color graphics (a formula or part of a figure) is encouraged. Pictures should be kept small with minimum detail, as the final graphics size can be quite small. There are two TOC formats possible: 5.5×4.5 cm or 11.4×3.5 cm.
In addition, for all manuscripts mentioned in Section 3, a maximum of five keywords should be given in alphabetical order. To aid online searching, at least two keywords should be taken from the Basic Keyword List, which has been developed for the readers of Wiley-VCH chemistry journals, including Angewandte Chemie International Edition, ChemBioChem, ChemPhysChem, ChemMedChem, ChemSusChem, ChemElectroChem, Chemistry–A European Journal, Chemistry–An Asian Journal, European Journal of Inorganic Chemistry, European Journal of Organic Chemistry, and Advanced Synthesis & Catalysis.
This catalogue is subdivided to facilitate the search for keywords, but can also be completely searched. Some of the keywords are used in more than one area. As with all such records, a few guidelines facilitate its use, and these are briefly explained below:
1. At least two of the maximum of five keywords assigned to an article must come from this list.
2. Named reactions will be incorporated only in exceptional cases. Generally the reaction type is selected instead. For example, Diels–Alder reactions will be found under "cycloadditions" and Claisen rearrangements under "rearrangements".
3. Heteroanalogues of compounds are mainly classified under the C variants, for example, (hetero)cumulenes, (hetero)dienes. A few aza and phospha derivatives are exceptions.
4. Compounds with inorganic components that are central to the article are listed under the element, for instance, iron complexes under "iron" and, if appropriate, the ligand type. Some group names such as "alkali metals" exist alongside the names of important members of the group, for example, "lithium". In such cases the group name is used for these members only when comparative studies are described. The members that do not appear separately are also categorized under the group name.
5. A keyword in the form "N ligand" is only chosen if a considerable portion of the paper deals with the coordination of any ligand that coordinates through the atom concerned (in the example, nitrogen).
6. Spectroscopic methods are assigned as keywords only if the article is about the method itself or if the spectroscopic technique has made an important contribution to the problem under investigation.
7. "Structure elucidation" is intended only if the crux of the paper is a structural elucidation or if a combination of several spectroscopic techniques were needed for conclusive solution of the structure.
8. An attempt has been made to avoid synonyms and to select more general concepts rather than specialized terms. Thus the term "double-decker complexes" is excluded in favor of "sandwich complexes".
9. Enzymes should be assigned to one of the six main enzyme classes (hydrolases, isomerases, ligases, lyases, oxidoreductases, transferases).
This list is a "living" catalogue, flexible enough to absorb new developments in chemistry. We therefore welcome all suggestions from our readers and authors that might improve its user-friendliness.
4.11. Crystal Structure Analysis
Prior to manuscript submission, the authors must deposit their crystal structural data or update data that are already available, so that referees can retrieve the information directly from the database. Please use the free online Checkcif service provided by the International Union of Crystallography. Please ensure that the data deposited with the database are identical to those in the manuscript.
If a crystal structure analysis is not an essential part of the paper, only a footnote is required indicating where the detailed results can be found. Otherwise, the following data should be given in the manuscript: crystal dimensions, crystal system, space group, unit cell dimensions and volume, ρcalcd, 2θmax, radiation, wavelength, scan mode, temperature of measurement, no. of measured and independent reflections, no. of reflections included in refinement, σ limits, whether and how Lorentzian polarization and absorption corrections were performed (μ, min/max transmission), method of structure solution and program, method of refinement and program, no. of parameters, treatment of H atoms. R, wR, whether refined against |F| or |F2|, residual electron density, and the database at which the detailed results are deposited. An ORTEP-type plot will not be reproduced when it merely serves to confirm the structure of a synthetic intermediate.
For organic and organometallic compounds: Send your data including author and journal details in CIF format as a plain text ASCII file by email to the Cambridge Crystallographic Data Centre (CCDC, 12 Union Road, Cambridge CB2 1EZ (UK); tel: (+44)1223-336-408; fax: (+44)1223-336-033; e-mail: firstname.lastname@example.org; see also WWW: http://www.ccdc.cam.ac.uk/conts/depositing.html). The data will be assigned a registry number, which should be included with the following standard text in the manuscript: "CCDC-... contain(s) the supplementary crystallographic data for this paper. These data can be obtained free of charge from The Cambridge Crystallographic Data Centre via http://www.ccdc.cam.ac.uk/data request/cif."
For inorganic compounds: The Fachinformationszentrum Karlsruhe only accepts data deposited in electronic form (in CIF format). Send the data by e-mail to FIZ, 76344 Eggenstein-Leopoldshafen (Germany); tel: (+49)7247-808-205; fax: (+49)7247-808-666; e-mail: email@example.com; WWW: fiz-karlsruhe.de under "Products". You will be given a CSD number, which should be included with the following standard text in the manuscript: "Further details of the crystal structure investigation(s) can be obtained from the Fachinformationszentrum Karlsruhe, 76344 Eggenstein-Leopoldshafen, Germany (fax: (+49)7247-808-666; e-mail: firstname.lastname@example.org) on quoting the depository number CSD-... ."
4.12. Supporting Information
Detailed facts and data of importance to specialist readers can be submitted as Supporting Information and will be made accessible together with the manuscript. This material is peer-reviewed and must therefore be included with the original submission. Supporting Information should not include crystallographic data that are available from the relevant databases. Color and animated multimedia applications are welcome for the Supporting Information.
To submit multimedia files that exceed 5 MB in size, please save them on your web server, but do not link to them. Send us the URL so we can download the files and make them available to referees and, if accepted, to readers. Please use suitable compression technology to avoid exceedingly large movie files (>10 MB) for the benefit of referees′ and readers′ bandwidth and storage capacity. Also, please make sure that your movies are saved in a common format (such as MPEG, AVI, QuickTime, GIF) that can be played on at least two different computer platforms (out of Windows/MacOS/Linux). Smaller files can simply be sent as an e-mail attachment.
4.13. General Remarks
Spelling may be British or American English, but consistency should be maintained within a manuscript. Authors are asked to make their manuscripts suitable for a heterogeneous readership of chemists and biologists and to be considerate to our many readers for whom English is a foreign language—please use a simple, clear style and avoid jargon.
Abbreviations and acronyms should be used sparingly and consistently, following the system of abbreviations and symbols recommended by IUPAC. Where they first appear in the text, they should—apart from the most common ones such as NMR, IR, or UV—be defined. You may prefer to explain large numbers of abbreviations and acronyms in a Glossary at the end of the text. Names of organisms should comply with genetic conventions, with genus and species names written in italics and spelled out in full on first appearance. Abbreviations for genes should be written in lower-case letters and italicized, while those of the corresponding protein products should start with a capital letter and should not be italicized (e.g., hsp70 and Hsp70, respectively). Enzyme names should be accompanied by the respective Enzyme Commission (EC) numbers.
Suggestions for the cover picture (18 cm wide×17 cm high; please do not place graphical objects within 20 mm of the edges) with an explanatory text (approximately 500 characters) beginning with "The cover picture shows...", are welcome, at the latest with the upload of the production material following acceptance of the manuscript. The cover picture is chosen by the Editor shortly before an issue is to be published. Part of the additional cost for selection and review process must be paid for by the author. Details will be provided upon selection of the cover picture.
5. Guidelines for the Preparation of Final Revised Versions of Manuscripts
The final revised version of the manuscript (production material) should be submitted after the paper has been accepted for publication either as a compressed file through your homepage, by e-mail, or as an uncompressed file on disk. Please note however, that the preferred method of submission of the final versions of manuscript is through your personal homepage on Editorial Manager.
To save unnecessary work with the electronic version of the text, please ensure your manuscript fulfills the following criteria:
1. Graphics should not be integrated in the text. Please store each chemical formula, figure, and scheme in a separate file. Though several graphics programs and formats can be used by the editorial staff and the printer, they are not equally suitable. To ensure trouble-free reproduction of the electronic graphics files, it is important to refer to the information given in the Guidelines for the Preparation of Graphical Material on our homepage (www.chemcatchem.org). Only in the case of Supporting Information should the graphics be present as imports in the file and not as separate files.
2. The preferred word-processing program is Microsoft Word for Windows or Macintosh. Files should preferably be stored in Word format. Documents prepared with other word-processing programs should be converted if possible. ChemTex files, for example, cannot be used. Supporting Information should be saved as a separate document in Word, RTF, or PDF format.
3. Tables are edited in the text and therefore should not be sent as graphical elements. The tables should be set up with tabulators, not with the space bar or line breaks.
4. Avoid end-of-line word divisions. Please use only one font type, except for Greek letters, which should be typed in Symbol font.
5. The text should be typed as "continuous text", that is, with carriage returns only at the end of a paragraph, title, heading, and similar features. Formula numbers, and in the reference section, the year of publication (but not headings such as "Table 1" or "Figure 1") should be in boldface. The symbols for 1 (one) and l ("ell"), 0 (zero) and O ("oh") should be distinct.
The correspondence author will receive page proofs, in most cases, as low-resolution compressed PDF files. They should be returned to the Editorial Office within three days. The main correspondence author will receive a complementary reprint PDF file, restricted to 25 printouts, free of charge.
