Decomposition of nitrous oxide over Fe-ferrierites. Effect of deposited oxygen on the framework oxygens studied by 18O isotopic exchange

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 labiliz...

Description
Summary: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.
