摘要

A simulated diesel engine exhaust gas feed was used to demonstrate the ability of a zeolite-supported Pd to adsorb NO at temperatures lower than 200oC. It is thought that the highly dispersed Pd on the zeolite exchange sites are the active sites. The NO storage capacity and NOx desorption temperature are both strongly affected by the zeolite framework structure. It may be possible to apply the studied materials for low-temperature NOx emission control.
