Mechanistic origin of the different activity of Rh-ZSM-5 and Fe-ZSM-5 in N2O …

Abstract. A temporal analysis of products (TAP) reactor was used to study relationships between the mechanism of direct N2O decomposition over metal-loaded zeolites and their resulting activity. Rh-ZSM-5 (prepared by incipient wetness) and Fe-ZSM-5 (prepared by liquid-ion exchange) were chosen as prototypic catalysts displaying low (650 K) temperature activity, respectively. Transient studi…
