Abstract
We present results for H2 production by reforming of oxygenates on Pt-based bimetallic surfaces using temperature-programmed desorption (TPD), high-resolution electron energy loss spectroscopy (HREELS) and density functional theory (DFT) calculations. Methanol, ethanol, ethylene glycol, and glycerol were employed as probe molecules. The formation of bimetallic surfaces with a 3d metal monolayer on Pt(111), designated 3d-Pt-Pt(111), led to increased H2 production as compared to the parent metal surfaces. The combined experimental and DFT results suggest that the reforming activity tracks the energy of the surface d-band center of various monometallic and bimetallic surfaces.
