The Inside Cover picture shows a polymer electrolyte membrane reactor device used for the electroreduction of biomass derivatives, in which the hydrophobicity of the diffusion layer (DL) greatly influences the hydrogenation performance of two model biomass derivatives. Hydrophobic carbon paper repels aqueous solutions, but highly volatile butanone can permeate in vapor form and achieve a high hydrogenation rate, whereas for nonvolatile maleic acid high mass‐transfer resistance prevents hydrogenation. With a hydrophilic DL, aqueous solutions of maleic acid can permeate in liquid form and the performance reaches a similar level as that of butanone. More details can be found in the Full Paper by Chen et al. on page 288 (DOI: 10.1002/cssc.201402302 ).
