Abstract:
In this paper, LaMnO3 and LaMn0.7Cu0.3O3 perovskites 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 by photocatalytic process. XRD results show that the studied perovskites were synthesized in single phase perovskite structure. SEM result shows that the morphology of LaMnO3 and LaMn0.7Cu0.3O3 are as irregular shaped grains. Perovskite catalysts show a good activity in catalytic removal of CO. The conversion of CO by LaMnO3 and LaMn0.7Cu0.3O3 was 65% and 82% respectively in 24h at room temperature by photocatalytic process. LaMn0.7Cu0.3O3 was the optimum catalyst in catalytic oxidation of CO.
