High-temperature treatment of a mechanical mixture of CuO and H-MFI zeolite in the absence of O[sub 2] produced a Cu ion-exchanged zeolite catalyst with a high activity for the catalytic decomposition of NO to N[sub 2] and O[sub 2]. Cu is probably introduced as Cu[sup +] cations in zeolite ion-excha...
