In this paper, the surface reaction of NO thermal desorption and NO CH 4 reaction activity over Co MgO catalyst were investigated. The adsorpted NO undergoes extensive decomposition to form N 2 and N 2O. There are two N 2 peaks which are attributed to N (a) +NO (a) N 2+O (a) and 2N (a) N 2 reactions, respectively. There is only one N 2O peak which is attributed to N (a) +NO (a) N 2O reaction. Because the O (a) produced during NO decomposition remains on Co microcrystallites, no O 2 peak is observed. The ratio of CO 2 and N 2 in the products is near 1/2, which indicates that the reaction can be described as 4NO+CH 42N 2+CO 2+H 2O.
