摘要：

The catalytic combustion of benzene over a Ni-Mn mixed oxide supported on cordierite coated with CeO2 was investigated. The catalysts were prepared using a sol-gel method and characterized using BET, H-2-TPR, XRD, SEM and TEM. The catalysts calcined at 500 degrees C for 7 h with a Ni/Mn molar ratio of 1 exhibited the highest catalytic activity. When the concentration of benzene was 4.8 g/m(3) and the GHSV was 15,000 h(-1), the conversion was 94.3% at 300 degrees C. These results were primarily attributed to the catalyst structure and the synergistic activity of the NiMnO3 perovskite and crystalline CeO2.
