Abstract:
Investigation of oxygen isotope exchange revealed a clear view on the mechanism of oxygen mobility in La1-xSrxMn(Fe)O3 mixed oxides and enabled to establish a correlation between the oxygen mobility and catalytic activity in methane combustion. Sr promotion resulted in the appearance of the fast pathway of oxygen diffusion in the bulk through oxygen vacancies. High reactivity of multiphase samples correlated well with the appearance of highly defective layer-structured (La1-ySry)2Mn(Fe)O4 perovskites on the surface which makes layer-structured phases promising catalysts for methane combustion.
