Mixed oxides of manganese-copper and manganese-copper-lanthanum with the mole ratio of Cu/ Mn=0.2
and Mn/La=1 have been prepared and evaluated in CO combustion. The gel combustion method used for the synthesis
of MnCu0.2Ox and LaMnCu0.2O3+d mixed oxides is adequate to obtain catalysts with excellent catalytic performance in
combustion reactions. Catalysts were characterized by means of BET, XRD, H2-TPR. The catalytic activity of the
perovskite samples (for low-temperature oxidation) was measured using a quartz reactor with an inlet gas containing
CO as pollutant gas, O2 and Ar as an inert gas. The mixed oxide catalysts showed high activity for the catalytic CO
oxidation reaction. LaMnCu0.2O3 achieved the same CO conversion at lower temperatures than to Cu0.2MnOx.
