The cover picture shows the production of hydrogen and carbon monoxide through reforming of oxygenates such as glycerol, ethylene glycol, and ethanol over a Ni monolayer on Pt(111) surface, designated Ni‐Pt‐Pt(111). This bimetallic surface exhibits stronger interactions with adsorbates as compared to unmodified Pt(111), increasing the activity for CH and OH scission reactions of interest in oxygenate reforming. In their Communication on page 524 ff., M. A. Barteau et al. report that the reforming activity of glycerol on the Ni‐Pt‐Pt(111) surfaces is increased as compared to that on Pt(111), Ni(111), and Pt‐Ni‐Pt(111) surfaces. The trend of glycerol reforming activity is similar to previous results for ethylene glycol and ethanol, with increasing activity as the surface d band center shifts closer to the Fermi level. The results demonstrate that the smaller oxygenates can be used as good models for reforming of larger, biomass‐derived oxygenates.
