摘要：

The catalytic activity of the Pt/gamma-Al2O3/Ce0.5-xZr0.5-xMn2xO2 monolithic catalyst for the low-temperature catalytic combustion of cooking fume in a fixed-bed reactor was studied with a series of Ce0.5-xZr0.5-xMn2xO2 complex oxides, and the effect of the Mn amount in Pt/gamma-Al2O3/Ce0.5-xMn2xO2 was further investigated. The catalyst was characterized by X-ray diffraction (XRD), N-2 adsorption, and H-2-temperature-programmed reduction (H-2-TPR). XRD results revealed that Pt was well dispersed on the gamma-Al2O3 support and Ce0.5-xZr0.5-xMn2xO2 matrix. H-2-TPR and N-2 adsorption measurements showed the catalyst activity in the order x = 0.10 > x = 0.15 > x = 0.05 > x = 0 > x = 0.20. Pt/gamma-Al2O3/Ce0.4Zr0.4Mn0.2O2 had the highest activity (T-90 = 495 K).
