Abstract
About 50-75% of oxygen captured during decomposition of N2O at 200 °C over Fe-FER (Fe/Al 0.03-0.6) was exchanged by 18O at room temperature. Complete desorption of captured oxygen containing mostly 16O isotope was reached at higher temperature. The 18O deficiency was rationalized by assuming labilization of the framework oxygen in Fe-FER.
