Copper cation exchanged ZSM-5 zeolites are effective catalysts for the NO decomposition reaction. The present studies have revealed that the conversion of the reaction NO {yields} 1/2N{sub 2} + 1/2O{sub 2} is intrinsically stoichiometric, and complete conversion can be obtained over a Cu-ZSM-5 catalyst. Operated in this way the undesirable side reaction NO + 1/2O{sub 2} {yields} NO{sub 2} can be avoided. The decomposition reaction was inhibited, but not poisoned, by 200 Torr of O{sub 2}.
