Abstract The Ce0.8Mg0.2BO3(B=Cr, Mn, Fe, Co, Ni, Cu)series catalysts were prepared by co-precipitation method using NH4HCO3 as precipitant. The structures were characterized by XRD, BET, H2-TPR, TG-DSC, FT-IR and SEM, and its performance catalytic on methane combustion was tested. The results show that the preparation of Ce0.8Mg0.2BO3 (B=Cr, Mn, Fe, Co, Ni, Cu) catalysts with different ions by co-precipitation method can form a complete perovskite after calcination at 800℃. The catalyst Ce0.8Mg0.2NiO3 shows an excellent activity for methane combustion (the conversion of 10% and 90% are obtained at 410℃ and 547℃, respectively).
