摘      要：Complete oxidation of benzene over supported manganese oxides catalysts was *** supports Ce0.5＋xZr0.4–xLa0.1O1.95-Al2O3 （x=0,0.1,0.2,0.3,0.4）,and CeO2-Al2O3 were prepared by co-precipitation method,and manganese oxides （MnOx） catalysts were prepared by incipient wetness *** activity was performed in a conventional fixed bed flow *** these catalysts,MnOx supported on Ce0.8Zr0.1La0.1O1.95-Al2O3 was found to have the highest catalytic activity for benzene *** complete conversion temperature of benzene on MnOx/Ce0.8Zr0.1La0.1O1.95-Al2O3 was 328 *** catalysts were characterized by X-ray diffraction （XRD）,Brunauer-Emmett-Teller （BET） specific surface area,X-ray photoelectron spectra （XPS） and H2-temperature programmed reduction （H2-TPR）.The results of BET and XRD measurements indicated that the addition of ZrO2 improved the textural *** measurements showed that MnOx was composed of MnO2 and *** catalysts reported in this work have significant potential in industrial application for their high performance and low cost.
