Abstract

FTIRS combined with ¹⁵N and ¹⁸O isotope substitution and TPD have revealed that nitrates are the most abundant ad-NO_x species on over-exchanged Cu- and Co-ZSM-5 zeolites. The transformation rates of such species under the action of a propane - oxygen mixture were found to be comparable and sufficiently high to afford steady-state catalytic activities. A scheme of the reaction mechanism including C, N -containing intermediates detected in this work is suggested.
