8_09/2015Cover Picture: Titania-Supported Catalysts for Levulinic Acid Hydrogenation: Influence of Support and its Impact on γ-Valerolactone Yield (ChemSusChem 9/2015)

The Front Cover picture shows that RuO2 is strongly attached to rutile phase of titania, which serves as a support for the Ru catalysts, whereas the anatase form of titania disables the good metal dispersion. This knowledge was applied to the synthesis of a very active catalyst for levulinic acid hydrogenation towards γ-valerolactone. More details on the influence of various morphologies and phases of titania on the catalytic performance in levulinic acid hydrogenation can be found in the Full Paper by Ruppert et al. (DOI: 10.1002/cssc.201403332).

8_09i/2015Inside Cover: Structure–Property Relationships: Asymmetric Alkylphenyl-Substituted Anthracene Molecules for Use in Small-Molecule Solar Cells (ChemSusChem 9/2015)

The Inside Cover picture illustrates two different crystalline structures in the solar cell devices. It depicts a series of asymmetric small conjugated molecules based on anthracene that were used in a systematic investigation of the structure–property relationships in solar cell devices prepared by using films of these molecules. One has a naphthalene unit and consists of amorphous domains without crystallites, whereas the other has a thiophene linker, which results in a randomly ordered crystalline structure. We focused on how the thiophene spacer influenced the nanoscale crystalline characteristics of the active layers and the resulting device performances. Our results can be used to guide the design and optimization of new high-performance anthracene-based small molecules.

8_09c/2015Inside Back Cover: Activation of Ultrathin Films of Hematite for Photoelectrochemical Water Splitting via H2 Treatment (ChemSusChem 9/2015)

The Inside Back cover picture shows ultrathin films of α-Fe2O3 before and after treatment in 5 % H2 in Ar at 450 °C. The hydrogen treatment creates oxygen vacancies in the iron oxide lattice, resulting in a non-stoichiometric hematite phase that is active for photoelectrochemical water oxidation. Electrochemical impedance spectroscopy reveals the buildup of a surface state capacitance that is only present for the hydrogen treated films when under illumination, at the point of photocurrent onset. A concomitant decrease in charge trapping resistance suggests that this is due to a build-up of photogenerated holes at the surface of the H2-treated films, which allows the water oxidation reaction to proceed. More details can be found in the Full Paper by Moir et al. on page 1557 (DOI: 10.1002/cssc.201402945).

8_09b/2015Back Cover: Photoelectrochemical Water Oxidation Efficiency of a Core/Shell Array Photoanode Enhanced by a Dual Suppression Strategy (ChemSusChem 9/2015)

The Back Cover picture shows a core/shell array photoanode and its application in photoelectrochemical water oxidation. The photoanode consists of a TiO2 nanorod array (core) and ultrathin phosphated double-hydroxide (shell), which results in significantly improved photogenerated carrier separation. Nearly 100 % oxidative efficiency for PEC water oxidation was achieved. In addition, the hydroxide sheath could efficiently inhibit the oxygen reduction reaction. This strategy enables the simultaneous suppression of surface carrier recombination and back reactions, which is promising to enhance the water oxidation efficiency of the currently prevailing photoanodes. More details can be found in the Full Paper by He et al. on page 1568 (DOI: 10.1002/cssc.201403294).
