英文摘要Ag-ZSM-5 catalysts were investigated for the selectively catalytic reduction of NO by methane in the excess of oxygen. The adsorption properties of NOx and the reaction of absorbed NOx with CH4 were studied through TPD and TPSR measurements. NOx was effectively and selectively reduced by CH, over Ag-ZSM-5 catalysts. The co-adsorption of NO and O-2 over Ag-ZSM-5 catalyst led to the formation of adsorbed NO3 species, which could be effectively reduced by CH4. Even in the presence of O-2, NO3 species were more reactive than O-2. The priority of CH4 reaction with surface NO3-species to form Nz was clearly observed.
