The Cover shows Ag species introduced to the surface of Raney Ni catalyst. In their Full Paper, B. Chen et al. investigate the role of bimetallic effects on the selective cleavage of C−O and C−C bonds in glycerol hydrogenolysis at high pH values. Compared to Raney Ni, the optimal Raney Ni6Ag catalyst is more active in glycerol conversion and efficient for C−O bond cleavage. Our results suggest that, on Ni catalysts, the adsorbed species hydrogenation is the most likely rate‐limiting step in glycerol hydrogenolysis under alkaline conditions. The Ag additive enhances the hydrogenation ability of Ni catalysts, which should be related to the tougher adsorbed strength of hydrogen and the inferior adsorbed strength of substrates on Ni sites due to the formation of Ni−Ag alloys. More information can be found in the Full Paper by B. Chen et al. on page 1929 in Issue 11, 2016 (DOI: 10.1002/cctc.201600239).
