Electrochemical oxidation of carbon monoxide: From platinum single crystals to low temperature fuel catalysts. Part II: Electrooxidation of H2, CO and H2/CO mixtures on well characterized PtMo alloy

Abstract

The oxidation of hydrogen and hydrogen-carbon monoxide mixture has been investigated on well-characterized metallurgically prepared platinum-molybdenum (PtMo) alloys. It was concluded that the optimum surface concentration of molybdenum is near 23 mol.% Based on experimentally detemined parameters and simulations, the mechanism of the oxidation of CO/H2 mixtures is discussed.
