Oxidation Of Carbon Monoxide

The electrochemical oxidation of carbon monoxide and the interfacial structure of the CO adlayer (COads) on platinum low index single crystals, Pt(111), Pt(100) and two reconstruction of Pt(110), were examined using the rotation disk electrode method in combination with the in situ surface X-ray diffraction scattering technique. The mechanism of CO oxidation is discussed on the basis of the findings that, depending on the potential, two energetic states ofCOads exist on the platinum surfaces. Thus, at lower potentials, weakly bonded states (COads,w) and at higher potentials strongly bonded states (COads,s) are formed. The mechanism of the oxidation of hydrogen-carbon monoxide mixtures is also proposed.

Oxidation Of Carbon Monoxide

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/H2 mixtures is discussed.
