摘要：
V2O5/TiO2 catalyst with 3% (w/w) V loading has been prepared by sol-gel method. The characterization results of the catalyst structure and catalytic activity show that VO (X) state is strongly dependent on the calcination temperature. Little effect is found for phase structure of TiO2 support on catalytic activity. High catalytic activity in wide temperature range (240-420 A degrees C) is observed for the catalysts calcinated at different temperatures at a space velocity of 50,000 h(-1). Space velocity and alkali metal oxides strongly influence the catalytic activity of the catalyst which was calcinated at 450 A degrees C, furthermore, the one has high tolerance to SO2 in our test conditions.
