Abstract. Reaction kinetics measurements were carried out to study the conversion of aqueous solutions of glycerol (30 and 80 wt%) over carbon-supported Pt and Pt–Re catalysts at temperatures from 483 to 523 K. The results of these studies show that the turnover frequencies for production of H2, CO, CO2, and light alkanes (primarily methane) all increase upon the addition of Re to Pt/C ca…
Abstract. This study used a combination of density functional theory (DFT) and temperature-programmed desorption (TPD) to determine trends in the hydrogenation activity of cyclohexene on several bimetallic surfaces prepared by modifying Pt(111) with 3d transition metals (Fe, Co, Ni, and Cu). The hydrogen binding energy (HBE) on the subsurface Pt-3d-Pt(111) “sandwich” structures was sign…
The dehydrogenation and decarbonylation of ethylene glycol and ethanol were studied using temperature programmed desorption (TPD) on Pt(111) and Ni/Pt(111) bimetallic surfaces, as probe reactions for the reforming of oxygenates for the production of H2 for fuel cells. Ethylene glycol reacted via dehydrogenation to form CO and H2, corresponding to the desired reforming reaction, and via total…
