| 摘要: |
A series of VOx-TiOx/SBA-15 catalysts was prepared by the grafting method. The catalysts were characte-rized by different techniques such as N2-sorption, TPR, UV-Vis and NH3-TPD in order to verify the vanadium and ti-tanium species, and their catalytic properties were investigated for the partial oxidation of toluene. The results show that vanadium mainly existed in the forms of isolated tetrahedral and octahedral species at the low loadings. The in-troduction of a certain amount of titanium improved the dispersion of vanadium on the support and then the catalytic performance for toluene oxidation at the same vanadium content. Both toluene conversion and benzaldehyde selec-tivity, showed the maximum values and then decreased with increasing the amount of titanium in the catalyst. |
