TPD and TPR studies on the reaction between adsorbed NOx species and CH4 over Cu-zeolite
NO3-type and NO2-type adsorbed species are formed on Cu-ZSM-5 together with adsorbed O species at 523 K in the decomposition of NO accompanied by the evolution of N-2, N2O, and NO2. NO3-type adsorbed species formed on Cu-ZSM-5 is well reduced with CH4 around 570 - 600 K, while NO2-type adsorbed species formed on Cu-ZSM-5 was less active on the reduction with CH4.
