      The cover picture, based on the Full Paper by Akihide Iwase, Hideki Kato, and Akihiko Kudo on p. 873, shows photocatalytic water splitting. In their contribution, the team of scientists from the Tokyo University of Science describes how the alkaline earth metal ions Ca, Sr, and Ba are doped into a NaTaO3 photocatalyst. The doped NaTaO3 particles exhibit surface nanostep structures; the formation and structure of the surface nanosteps being controllable through the amount of dopant. Doping enhanced the photocatalytic water splitting activity of NaTaO3, and the photocatalytic activity could be improved further by loading of a NiO cocatalyst.

    1. Adsorbent Materials for Carbon Dioxide Capture from Large Anthropogenic Point Sources (pages 796–854)

      Sunho Choi, Jeffrey H. Drese and Christopher W. Jones

      Version of Record online: 3 SEP 2009 | DOI: 10.1002/cssc.200900036

      Getting the point: As concern over the rise in atmospheric CO2 concentration has increased, recent research efforts have focused on capturing CO2 from large anthropogenic point sources. Many solid adsorbent classes, including zeolites, activated carbons, calcium oxides, hydrotalcites, organic–inorganic hybrids, and MOFs, have been considered as alternatives to the current benchmark aqueous amine absorption technology for CO2 capture.

    1. Base-free Pd/TOMPP-Catalyzed Telomerization of 1,3-Butadiene with Carbohydrates and Sugar Alcohols (pages 855–858)

      Peter J. C. Hausoul, Pieter C. A. Bruijnincx, Robertus J. M. Klein Gebbink and Bert M. Weckhuysen

      Version of Record online: 25 AUG 2009 | DOI: 10.1002/cssc.200900115

      Sugar and alcohol—a superior combo: The telomerization activity of the Pd/TOMPP catalyst is screened using thirteen different biomass-derived carbohydrates and sugar alcohols. High substrate conversions are achieved by using low Pd loading and without the use of an added base. In terms of butadiene conversion, a clear structure–activity relationship is found, which is in line with the series: sugar alcohols>sucrose>aldohexoses>aldopentoses>ketohexoses.

    2. Dramatic Advancements in the Saccharide to 5-(Chloromethyl)furfural Conversion Reaction (pages 859–861)

      Version of Record online: 14 SEP 2009 | DOI: 10.1002/cssc.200900136

      CMF from biomass ten times faster: Sugars, cellulose, and corn stover are converted into 5-(chloromethyl)furfural (CMF) in only 3 h by digestion with hydrochloric acid in a closed, biphasic reactor at 80–100 °C in >80 % isolated yield. Under the same conditions, chitin gives a mixture of CMF and levulinic acid in a combined yield of 74 %.

    3. Organocatalytic, Asymmetric Aldol Reactions with a Sustainable Catalyst in a Green Solvent (pages 862–865)

      Michael North, Francesca Pizzato and Pedro Villuendas

      Version of Record online: 2 SEP 2009 | DOI: 10.1002/cssc.200900144

      Thumbnail image of graphical abstract

      Green solvents: Cyclic carbonates (ethylene and propylene carbonate) make excellent, sustainable solvents for (S)-proline catalyzed cross-aldol reactions between ketones and aromatic aldehydes. With cyclohexanone as the enamine precursor, reactions in ethylene carbonate gave much better results compared to propylene carbonate, whereas with acetone as the enamine precursor, reactions in both solvents gave similar results.

    1. Titania Nanocrystals and Adsorptive Nanoporous Polymer Composites: An Enrichment and Degradation System (pages 867–872)

      Yonglai Zhang, Shu Wei, Wei Zhang, Yi-Jun Xu, Sen Liu, Dang Sheng Su and Feng-Shou Xiao

      Version of Record online: 31 AUG 2009 | DOI: 10.1002/cssc.200900100

      Titania nanocrystals and adsorptive nanoporous polymer composites are prepared by a two-step solvothermal pathway. These composites are designed as an enrichment and degradation system for the elimination of environmental pollutants. The bifunctional materials could be used to decontaminate organic pollutants in both water and the atmosphere.

    2. The Effect of Alkaline Earth Metal Ion Dopants on Photocatalytic Water Splitting by NaTaO3 Powder (pages 873–877)

      Akihide Iwase, Hideki Kato and Akihiko Kudo

      Version of Record online: 3 SEP 2009 | DOI: 10.1002/cssc.200900160

      Thumbnail image of graphical abstract

      Quick-step: The doping of alkaline earth metal ions into NaTaO3 gives fine particles and surfaces with nanometer-scale step structures (see figure). The materials show dramatically improved activities in the photocatalytic water splitting reaction.

    3. Investigations of the Conversion of Inorganic Carbonates to Methane (pages 878–882)

      Dinesh Jagadeesan, Muthusamy Eswaramoorthy and C. N. R. Rao

      Version of Record online: 3 SEP 2009 | DOI: 10.1002/cssc.200900152

      Thumbnail image of graphical abstract

      Methanation: The conversion of transition metal carbonates to methane in the presence of hydrogen is investigated. The reduced form of cobalt–calcium carbonate acts as a good catalyst for the efficient conversion of calcium and magnesium carbonates to methane, which is an alternative strategy for the capture and reuse CO2.

    4. Chemistry of Ethylene Glycol on a Rh(100) Single-Crystal Surface (pages 883–886)

      Maarten M. M. Jansen, Ben E. Nieuwenhuys and Hans Niemantsverdriet

      Version of Record online: 31 AUG 2009 | DOI: 10.1002/cssc.200900153

      Thumbnail image of graphical abstract

      The adsorption and decomposition of ethylene glycol on Rh(100) are studied with temperature-programmed reaction spectroscopy and reflection absorption infrared spectroscopy. Ethylene glycol adsorbs onto the surface via the hydroxyl groups. At 150 K, an ethylenedioxy intermediate is observed and at high coverage, a portion of the ethylene glycol molecules dehydrogenate forming a monodentate species. These intermediates decompose further at ca. 290 K.
