Solid solutions La0.5Ca0.5Mn1-xFexO3 synthesized by the method of polymer-salt compositions at a temperature of 900° C with the perovskite structure were tested in the methane oxidation reaction. It was shown that at 600° C, complete conversion of methane occurs for all compositions, however, the nature of the dependence of the degree of conversion for lower temperatures is not linear and depends on the chemical composition. The formation of planar defects in the direction of crystallographic planes (101) in the perovskite structure at the stage of the synthesis of solid solutions and the appearance of nanoparticles of Ca-Mn oxides on the surface of perovskite after participation after reaction were shown by the HRTEM method.
