CH4 reduction and NO decomposition reactions (original) (raw)

Reduction and decomposition of nitric oxide using methane as a reducing agent has been studied in the presence and absence of oxygen over Pd/TiO 2 catalysts. Temperature-programmed adsorption/desorption and reduction/oxidation behavior has been examined. Prereduced catalysts have shown significant reduction as well as decomposition activity. Isotopic labelling studies using 13CH4, 15N180, 15NO, and 180 2 have also been performed to investigate the interaction of NO and methane with the catalytic sites.
