Abstract:
In this paper, LaMn0.7B0.3O3 (B= Cu and Co) perovskite were synthesized by sol-gel auto combustion method and characterized by X-ray diffraction and scanning electron microscope. Activity of synthesized catalysts were evaluated in catalytic oxidation of CO. XRD results show that the studied perovskites were synthesized in single phase perovskite structure. The activity of catalysts improved due to partial substitution of Mn by Cu cation. T50% of CO conversion over LaMnO3, LaMn0.7Cu0.3O3 and LaMn0.7Co0.3O3 was 145, 85 and 155 ºC, respectively. LaMn0.7Cu0.3O3 was the optimum catalyst in catalytic oxidation of CO.
