The mutual interaction between NO and N2O on Cu-ZSM5 has been studied in experimental conditions in which both decomposition reactions occur. The oscillating behaviour observed in N2O decomposition is strongly influenced by the presence of NO, as the latter quenches the oscillations and stabilises the highest active state of the catalyst. A reaction mechanism is proposed to explain the experimental observations, based on the assumption that NO reduces the catalyst sites from Cu+2 to Cu+, via the formation of adsorbed species and gaseous NO2.

Abstract
The mutual interaction between NO and N2O on Cu-ZSM5 has been studied in experimental conditions in which both decomposition reactions occur. The oscillating behaviour observed in N2O decomposition is strongly influenced by the presence of NO, as the latter quenches the oscillations and stabilises the highest active state of the catalyst. A reaction mechanism is proposed to explain the experimental observations, based on the assumption that NO reduces the catalyst sites from Cu+2 to Cu+, via the formation of adsorbed species and gaseous NO2.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
