摘要：

The catalytic combustion of toluene over Fe-Mn mixed oxides supported on cordierite was investigated. The catalysts were synthesized by the impregnation method and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and BET specific surface area measurement. The effects of the mole ratio of Fe to Mn, the loading of Fe-Mn mixed oxides on the catalyst support and the calcination temperature were all investigated. The results indicate that Fe-Mn/cordierite catalysts with a 4 mol ratio of Fe to Mn, used with 10 wt% loading, and calcined at 500 degrees C showed the highest catalytic activities as measured by the oxidation of toluene. Compared to unsupported powder catalysts of Fe Mn mixed oxides, the Fe-Mn/cordierite catalyst showed higher activity for the catalytic combustion of toluene with less active component.
