Cover Picture: Enhancing H2 and CO Production from Glycerol Using Bimetallic Surfaces (ChemSusChem 6/2008)
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 C-H and O-H 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.
