| Abstract: | The oxidation state of Co, Pt and Rh containing MCM-41 after co-adsorption of NO, CH4, and O2 in the presence of water vapor was studied by in situ XANES experiments. All catalysts were oxidized after the adsorption
of NO and reduced after the co-adsorption of NO and CH4. The presence of water vapor did not influence the oxidation/reduction of Rh/MCM-41 and Pt/MCM-41, while Co/MCM-41 was oxidized
by the presence of H2O at reaction temperature.
