Abstract
Abstract The catalytic decomposition of NO has been investigated over various copper ion-exchanged zeolites. At 753 K the Cu2+-exchanged ZSM-5 zeolite with SiO2/Al2O3=23.3 and exchange level=100% showed a high and consistent activity for the reaction even at a contact time of 0.2–0.025 g.sec.cm−3 or GHSV=10000–80000 h-1. The IR, ESR, and TPD experiments made it possible to evaluate the number of Cu2+ ions which could adsorb NO molecules. It follows that the proportion of the copper ions available for NO adsorption is dependent on the zeolite structure, and the activity per cupric ion accessible to NO depends on the Al content of the parent zeolite.
