Abstract La-M-Co-O (M=Mn, Cr, Fe, Ni and Cu)/cordierite catalysts were prepared by complexation method with citric acid. BET, XRD, SEM, H₂-TPR and XPS technologies were used to characterize and analyze the performance and microstructure of these catalysts. Meanwhile, the influences of the types of transition metal, the amount transition metal and calcination temperature were studied. The results show that when the calcination temperature was 650℃, the active oxide particles supported on the surface of the catalysts were the most dispersed and displayed the best activity for chlorobenzene oxidation. And when the reaction temperature was 350℃, the conversion rate is as high as 96.4%. The main reason was that the catalysts displayed the structure of LaCoO₃ perovskite composite oxides attribute to the high calcination temperature, which was beneficial for improving the performance of catalytic oxidation of chlorobenzene over composite catalysts.
