In situ Raman spectroscopy studies on the methanol oxidation over silver surface

In situ surface Raman spectroscopy has been employed to investigate the oxidation of methanol on silver. The intermediates at various temperatures were identified. According to the results, the reaction pathways in the practical process were suggested and compared with the conclusion obtained under UHV condition previously. They showed a remarkably close agreement except the temperature at which the surface intermediates exist. All these results proved that the mechanism of methanol oxidation obtained under UHV condition is effective under the industrial conditions. (C) 1997 Elsevier Science B.V.
