High temperature performance and stability of Fe-FER catalyst for N2O decomposition

The scope of the study was to identify the performance and long-term stability of Fe-FER for N2O decomposition under conditions relevant for use as a secondary-level catalyst for N2O decomposition in the production of HNO3, i.e., in a complex gas phase mixture produced by NH3 oxidation and at temperatures between 750 and 850 °C. The 12 days aging did not induce the collapse of FER structure and Fe(II) cations relevant for N2O decomposition are present. Thus, Fe-FER is a potential candidate for HT N2O decomposition under realistic conditions.
