Influence of the LaMn1−xFexO3 (x = 0–1) Composition on Catalytic Activities in the Reactions Involving Oxygen

Perovskite samples of the LaMn1−xFexO3 (x = 0–1) series were prepared by Pechini method; their physicochemical properties studied using XRD, HRTEM, XPS, and BET, catalytic activity was estimated in nitrous oxide decomposition methane CO oxidation reactions. In reactions, all intermediate (0 < x 1) exhibited a lower normalized to unit surface area as compared extreme terms, whereas more active than terms series. Different dependences activities on composition obtained study for tested reactions involving catalyst oxygen are caused differences reaction mechanisms.
