摘要

The decomposition of N2O is strongly promoted by NO over Fe catalysts supported on zeolites (ex-framework FeMFI catalysts, sublimed Fe/ZSM-5, ion-exchanged Fe–ZSM-5, Fe- beta, and Fe–USY) and conventional supports (Fe/Al2O3 and Fe/SiO2) in a wide temperature range (550–900 K). Mixtures of NO and O2 in the N2O-containing feed lead to the same promoting effect as NO only. The promoting effect of NO is catalytic, and in ...
