Abstract

In oxygen transfer reactions V//2O//5 catalysts are considered as redox systems. Transition metal additives generally improve their catalytic activity, however, the probable influence of the transition metal on V//2O//5 is still questionable. The catalytic oxidation of CO as a toxic polluting material is of great practical importance. The kinetics of this reaction in the presence of catalysts such as vanadium pentoxide unsupported, supported and even doped with PdCl//2 has been studied in a pulse reactor connected to a GC and the chemical state of the catalysts exposed to CO or CO plus O//2 has been investigated by in situ XPS experiments using a KRATOS XSAM 800 instrument. The observed synergic effect is interpreted in terms of the increased liability of vanadium towards an alteration of its oxidation state in oxygen transfer reactions.
