    1. Cover Picture: Catalytic Synthesis of Neutral H2O2 Solutions from O2 and H2 by a Fuel Cell Reaction (ChemSusChem 12/2008) (page 957)

      The cover picture shows the scheme of a polymer electrolyte membrane fuel cell (PEMFC) reactor for the catalytic synthesis of neutral solutions of hydrogen peroxide from hydrogen and oxygen. The industrial synthesis of H2O2 is currently limited to the multistep anthraquinone method, and the production costs and transport limitations of H2O2 are serious disadvantages for its wider use. Thus, methods for its direct production from O2 and H2 are much sought after. In their Communication on page 988 ff., I. Yamanaka et al. report the safe and direct synthesis of neutral H2O2 solutions from O2 and H2 using a new active cathode comprised of a Co-tetraphenylporphyrin electrocatalyst on vapour-grown carbon fibre. A maximum concentration of 13.5 wt % (4.0 M) H2O2 was obtained at a current density of 90 mA cm−2 with a current efficiency of 42 % at 278 K.

    1. Cellulose Conversion under Heterogeneous Catalysis (pages 969–975)

      Paresh L. Dhepe and Atsushi Fukuoka

      Version of Record online: 19 NOV 2008 | DOI: 10.1002/cssc.200800129

      Tree-hugging chemistry: The conversion of cellulose (non-food biomass) into chemicals can be carried out with the aid of heterogeneous catalysis using solid acids or supported metals (Pt, Ru). Thus, sugar alcohols such as sorbitol and mannitol can be formed with high selectivity under relatively mild conditions and then further transformed into value-added products.

    1. CuI versus RuII: Dye-Sensitized Solar Cells and Beyond (pages 977–979)

      Neil Robertson

      Version of Record online: 28 NOV 2008 | DOI: 10.1002/cssc.200800214

      Copper for the scientist cunning at his trade: RuII complexes have long played the central role in the photochemical conversion of sunlight and dye-sensitized solar cells (DSSCs). Recently, however, the first examples of DSSCs sensitized by CuI polypyridyl complexes were reported. CuI complexes have comparable photophysical and electrochemical properties to RuII complexes and offer similar function with a cheaper and more abundant metal.

    1. Isoreticular MOFs as Efficient Photocatalysts with Tunable Band Gap: An Operando FTIR Study of the Photoinduced Oxidation of Propylene (pages 981–983)

      Jorge Gascon, María D. Hernández-Alonso, Ana Rita Almeida, Gerard P. M. van Klink, Freek Kapteijn and Guido Mul

      Version of Record online: 3 DEC 2008 | DOI: 10.1002/cssc.200800203

      Thumbnail image of graphical abstract

      Photo frame(work): The first spectroscopic evidence of metal-organic frameworks (MOFs) acting as photocatalysts has been obtained. Isoreticular MOFs act as efficient photocatalysts in the photooxidation of propylene. The band gap energy can be tuned by changing the organic linker. Among the MOFs tested, the 2,6-naphthalenedicarboxylic acid based IRMOF was the most active, showing a higher activity than ZnO.

    2. Rhodium Colloidal Suspensions Stabilised by Poly-N-donor Ligands in Non-Aqueous Ionic Liquids: Preliminary Investigation into the Catalytic Hydrogenation of Arenes (pages 984–987)

      Bastien Léger, Audrey Denicourt-Nowicki, Hélène Olivier-Bourbigou and Alain Roucoux

      Version of Record online: 28 NOV 2008 | DOI: 10.1002/cssc.200800194

      Thumbnail image of graphical abstract

      In a state of suspension: Colloidal suspensions of Rh0 nanoparticles stabilised by polynitrogen ligands such as 2,4,6-tris(2-pyridyl)-s-triazine were prepared in the ionic liquid l-n-butyl-3-methylimidazolium hexafluorophosphate ([BMI][PF6]) by chemical reduction of RhIII. The resulting suspensions of ligand-stabilised metallic nanoparticles were then applied as catalysts in the hydrogenation of arenes with excellent results.

    3. Catalytic Synthesis of Neutral H2O2 Solutions from O2 and H2 by a Fuel Cell Reaction (pages 988–992)

      Ichiro Yamanaka, Satoshi Tazawa, Toru Murayama, Ryo Ichihashi and Noriko Hanaizumi

      Version of Record online: 13 NOV 2008 | DOI: 10.1002/cssc.200800176

      Thumbnail image of graphical abstract

      Peroxide power: Neutral solutions of H2O2 can be produced directly and safely from O2 and H2 by using a fuel cell reaction. The most active and efficient cathode is a vapour-grown carbon fibre (VGCF) electrode coated with Co-tetraphenylporphyrin (0.05 wt %) on VGCF (2 mg cm−2). A maximum concentration of 13.5 wt % (4.0 M) H2O2 is obtained under optimized conditions at 278 K.

    1. Acceleration of Suzuki–Miyaura- and Stille-type Coupling Reactions by Irradiation with Near-UV-A Light (pages 993–996)

      Giovanni Imperato and Burkhard König

      Version of Record online: 25 NOV 2008 | DOI: 10.1002/cssc.200800187

      Thumbnail image of graphical abstract

      A little ray of light: Heating of a palladium catalyst that bears UV-A-absorbing phosphine ligands by selective UV-A irradiation in Suzuki–Miyaura- and Stille-type reactions leads to higher conversions of reactants at lower temperatures and an increased selectivity towards the cross-coupling product. Non-uniform heat distribution in the reaction mixture may cause this enhancement.

    2. Catalytic Hydrogenolysis of Aromatic Ketones in Mixed Choline–Betainium Ionic Liquids (pages 997–1005)

      Charlie Van Doorslaer, Joos Wahlen, Pascal G. N. Mertens, Ben Thijs, Peter Nockemann, Koen Binnemans and Dirk E. De Vos

      Version of Record online: 28 NOV 2008 | DOI: 10.1002/cssc.200800140

      Thumbnail image of graphical abstract

      Mild, green fairy liquids: After screening a wide range of ionic liquids, a binary mixture of choline and betainium bis(trifluoromethylsulfonyl)imide ionic liquids was selected as the reaction medium for the hydrogenolysis of aromatic ketones. This mixture of ionic liquids functions both as co-catalyst and as immobilization medium for the palladium catalyst, which can efficiently be recycled after decantation of the reaction products.

    3. A Practical and Benign Synthesis of Primary Amines through Ruthenium-Catalyzed Reduction of Nitriles (pages 1006–1010)

      Stephan Enthaler, Kathrin Junge, Daniele Addis, Giulia Erre and Matthias Beller

      Version of Record online: 25 NOV 2008 | DOI: 10.1002/cssc.200800185

      Thumbnail image of graphical abstract

      Benign by design: An easily accessible in situ catalyst composed of [Ru(cod)(methylallyl2)] and PPh3 has been developed for the environmentally benign hydrogenation of various nitriles to give primary amines. The developed procedure is significantly more benign than the well-known stoichiometric reductions with metal hydrides.

    4. Synthesis and Photocatalytic Activity of Zn2GeO4 Nanorods for the Degradation of Organic Pollutants in Water (pages 1011–1019)

      Jianhui Huang, Kaining Ding, Yidong Hou, Xinchen Wang and Xianzhi Fu

      Version of Record online: 3 DEC 2008 | DOI: 10.1002/cssc.200800166

      Thumbnail image of graphical abstract

      Cleaner water in a flash: Zn2GeO4 nanorods with improved physicochemical properties were prepared by a surfactant-assisted hydrothermal method. These nanorods are efficient heterogeneous photocatalysts that induce the formation of reactive hydroxyl radicals for the decomposition of organic pollutants in wastewater.

    5. Synthesis and Characterization of Novel Biopolyesters from Suberin and Model Comonomers (pages 1020–1025)

      Andreia F. Sousa, Alessandro Gandini, Armando J. D. Silvestre and Carlos Pascoal Neto

      Version of Record online: 28 NOV 2008 | DOI: 10.1002/cssc.200800178

      Thumbnail image of graphical abstract

      What a corker! Suberin, a major component of cork, is a valuable renewable resource for the preparation of novel hydrophobic polymeric materials whose properties resemble those of petroleum-based aliphatic polyesters. Moreover, polycondensation of the suberin monomers under emulsion polymerization conditions or using Candida antarctica lipase are beneficial approaches from a green perspective.
