| Abstract: | "ABO(3)-type perovskites (A = La, Ce; B = Mn, Ni) were prepared by sol-gel method, and applied for catalytic oxidation of toluene. The activity test results show that the activity of LaMnO(3) can be improved when a small amount of Ce and Ni are doped into the A and B sites of LaMnO(3), respectively. The effects of different calcination temperatures and different calcination time on the preparation of La-based perovskites were also investigated. The results illustrate that the toluene conversion of La(0.8)Ce(0.2)Mn(0.8)Ni(0.2)O(3) is the highest when the calcination temperature is 700 degrees C and the calcination time is 4 h in La(1-x)Ce(x)Mn(1-y)Ni(y)O(3) perovskites, and it requires lower reaction temperature when the conversion rate of toluene reaches 100% as compared to other catalysts, the T(90) is 295 degrees C (T(90), the temperature corresponding to the 90% of toluene conversion). Importantly, the mechanism of catalytic oxidation was also discussed. Therefore, the catalyst has potential prospects in the volatile organic compounds (VOCs) degradation" |
