Behavior of Active Oxygen During the Decomposition of Nitrous Oxide Over Fe-FER

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 deco...

Description
Summary: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.
