Correlation between activity of massive and supported La(-Sr)-Fe and CeO2 based mixed oxides in the reaction of hightemperature N2O decomposition and their capability to supply oxygen from the near subsurface layers to adsorbed species formed after N2O decomposition on the active surface sites was analyzed. Formation of heterostructured interfaces on the surface of intergrown composites or mixed solutions enriched by oxygen vacancies was shown to promote oxygen exchange in the surface and near subsurface layers thus hastening O2 desorption.
