Abstract:
Gas phase reactions of Mo+ and W+ ions with the molecules of various oxidants (NO, O2, N2O, CH2O, C2H4O) were studied using ion cyclotron resonance. In oxidation with N2O the mono-, di- and trioxide metal cations are formed consecutively. The trioxide MO3+ ions of both metals react with CO to form CO2 and MO2+ ions. In this way, catalytic reaction N2O + CO → N2 + CO2 occurs in the gas phase with MoO3+ /MoO2+ and WO3+/WO2+ couples as catalysts. The rate constants have been measured for both stages of the catalytic cycle as well as for the stages of the catalyst preparation. Metal-oxygen bond energies were estimated for MoOx+ and WOx+ species with various x. The mechanism of CO oxidation with MoOx+ and WOx+ cations as catalysts in the gas phase is discussed in comparison with that for the oxidation over classical solid oxide catalysts.
