Operando XAS study of the influence of CO and NO on methane oxidation by Pd/Al2O3

Methane oxidation on Pd/Al2O3 has been investigated using operando X-ray absorption spectroscopy (XAS) at the Pd K-edge. The influence of CO and NO on methane abatement has been addressed performing temperature programmed reaction runs while recording simultaneously XANES spectra. During CO oxidation Pd is reduced while methane conversion is shifted to higher temperature. NO strongly inhibits both CO and CH4 oxidation, despite the higher fraction of oxidized palladium.
