摘要：

Mno(x)-CeO2 mixed oxide catalysts prepared by sol-gel method were tested for the catalytic combustion of chlorobenzene (CB), as a model of chlorinated aromatic volatile organic compounds (CVOCs). MnOx-CeO2 catalysts with the different ratio of Mn/Ce + Mn were found to possess high catalytic activity for catalytic combustion of CB, and MnOx(0.86)-CeO2 was the most active catalyst, on which the complete combustion temperature (T-90%) of chlorobenzene was 236 degrees C. The stability of MnOx-CeO2 catalysts in the CB combustion was investigated. MnCx-CeO2 catalysts with high Mn/Ce + Mn ratios present high stable activity, which is related to their high ability to remove Cl species adsorbed and a large amount of active surface oxygen.
