Isotope exchange (I.E) of 18O2 for oxygen captured in Fe-FER after decomposition of nitrous oxide proceeds readily even at room temperature, provided that the amount of surface NO x species, formed as a secondary product of the N2O decomposition, is relatively low. If 18O2 is present during the decomposition of nitrous oxide above 250 °C, or if nitrous oxide labeled with 18O is employed, 18O appears also in NO x species, and I.E easily occurs with zeolite framework oxygens.
