7_04/2014Cover Picture: Syntheses of Biodiesel Precursors: Sulfonic Acid Catalysts for Condensation of Biomass-Derived Platform Molecules (ChemSusChem 4/2014)

The cover picture shows the utility of silica-supported alkyl sulfonic acid catalysts for the sustainable production of diesel fuel from biomass. A number of small furanic platform molecules are available from the acid-catalyzed dehydration of biomass-derived sugars. However, one of the main challenges to producing high quality biodiesel is selectively upgrading these small molecules into products appropriate for the diesel range (C11–C23). The silica-supported catalyst illustrated in the cover picture meets this challenge with high efficiency and recyclability without the need for a solvent, thereby contributing to sustainability of this green, alternative diesel precursor. The hydrophobic alkyl sulfonic acid functionality of this catalyst is the key for high activity as well as hydrolytic stability throughout the synthesis of the biodiesel precursors shown in this work. More detail is given in the Full Paper by Balakrishnan et al. on page 1078 (DOI: 10.1002/cssc.201300931), while more information about the research group is available in the Cover Profile (DOI: 10.1002/cssc.201400090).

7_04i/2014Inside Cover Picture: Cu2O/Reduced Graphene Oxide Composites for the Photocatalytic Conversion of CO2 (ChemSusChem 4/2014)

The inside cover shows a strategy to fabricate Cu2O/reduced graphene oxide (RGO) junction photocatalysts for the photoreduction of CO2 into solar fuel. With superior photoactivity for CO2 reduction, the junction further exhibits dramatically improved photostability. The perfect performance of the photocatalysts can be ascribed to the role of RGO as an efficient electron acceptor and a protection layer. The study by Tang et al. presents useful information for other photocatalysts modification for efficient CO2 reduction without the need of a noble metal cocatalyst; more details can be found in the Full Paper on page 1086 (DOI: 10.1002/cssc.201301194).

7_04b/2014Back Cover: Superior Pseudocapacitive Behavior of Confined Lignin Nanocrystals for Renewable Energy-Storage Materials (ChemSusChem 4/2014)

The back cover picture shows the materials used by Park et al. to produce a renewable hybrid electrode: it consists of lignin nanocrystals confined on reduced graphene oxides (RGOs). Using this electrode results in a large maximum capacitance (432 F g−1), which is close to the theoretically obtainable value of 482 F g−1 and sixfold higher than that of RGO (93 F g−1). Remarkable rate and cyclic performances are also achievable. The excellent capacitive performance is attributed to the fast and reversible pseudocapacitive behavior of quinone moieties and the synergistic interplay between lignins and RGOs. More details can be found in the Full Paper by Park et al. on page 1094 (DOI: 10.1002/cssc.201301061).
