Electrochemical oxidation of carbon monoxide: from platinum single crystals to low temperature fuel catalysts. Part Ⅱ: Electrooxidation of H_2, CO and H_2/CO mixtures on well characterized PtMo alloy

摘要

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 determined parameters and simulations, the mechanism of the oxidation of CO/H_2 mixtures is discussed.
