MeOx/Al2O3 and MeOx/CeO2 (Me = Fe, Co, Ni) catalysts for high temperature N2O decomposition and NH3 oxidation

Author affiliations

Abstract

A series of MeOx/Al2O3 and MeOx/CeO2 (Me = Fe, Co, Ni) compounds was prepared by incipient wetness impregnation and characterized by XRD, XPS, UV-vis DRS, differential dissolution phase analysis (DDPA). Their activity towards N2O decomposition and ammonia oxidation at 750–900 °C was shown to depend on oxygen mobility in the sample as characterized by steady state isotopic transient kinetic analysis (18O SSITKA) and dispersion of MeOx (Me = Fe) species. Obvious reverse “activity-FeOx dispersion” dependence was related to the change of contribution from oxygen transfer from the support to active sites through the Me–ceria or not improbably, the Me–alumina interface. It was shown that the high efficiency of CeO2 based samples in deN2O can be additionally increased by CeO2 supporting onto high surface area alumina.
