摘要：
The mechanism of N2O decomposition over an O-18-labeled Fe-ZSM-5 catalyst was studied. The isotope distribution of the O-2 produced during N2O decomposition was statistical. This shows that O-2 was formed from a pool of equilibrated surface oxygen atoms. The size of the pool was 1.0 O/Fe, i.e. most or all of the iron clusters took part in the reaction. The reactivity of the oxygen atoms in the pool was low. They did not exchange with O-18(2) to a significant extent.
