| 英文摘要 | the effects of alkali metal on the toluene catalytic oxidation were studied over the manganese oxide supported on sba-15. their properties were characterized by temperature programmed reduction (tpr), x-ray diffraction (xrd), diffuse reflectance spectra (drs) and fourier transform infrared (ftir) techniques. it was found that the k/mn molar ratios over the range of 0.1/1-0.3/1 greatly influenced the structure of the catalyst and the activity for toluene oxidation. when the k/mn molar ratio was lower than 0.125/1, it led to a decrease in the dispersion of metal oxide particles and the reducibility, resulting in low reactivity for toluene oxidation. increasing the k/mn molar ratios to 0.15/1-0.18/1 resulted in the transformation of parts of mno2 into mn2o3, and accompanying with the high dispersion of metal oxides and better reducibility. the catalytic activity was obviously increased when the k/mn molar ratio was 0.15/1-0.18/1. the reactivity of the sample with k/mn above 0.18/1, however, declined sharply due to the blocking of active sites by k. two important adsorption sites existed on the kmn/sba-15 system, in which one was isolated oh groups on the sba-15 and the other was the activated si-o-mn bond under the effect of k.
