Abstract

La_(1-x)Ce_xMn_0.6Fe_0.4O_3(x=0-0.5)compounds were synthesized by the citrate method. The samples were characterized by X-ray diffraction, IR and BET. XRD and IR results show that the different content of Ce in the perovskite oxides affects perovskite structures. It is a single perovskite when Ce content is 20%, and there are the phases of perovskite and CeO_2 when Ce content is over 20%. BET result shows that perovskite reaches a maximum surface area when x equal to 0.2. The perovskite loaded on supporter exhibits great catalytic activity when x is up to 0.2.
