采用溶胶-凝胶法制备了超微孔材料（TiPW/SA ），通过FT-IR和N2吸附脱附对其进行表征。并以模拟汽油（二苯并噻吩硫质量分数为300 m g/kg ）氧化脱硫反应为探针反应，考察其催化氧化吸附脱硫性能。结果表明，TiPW/SA保持了Keggin结构，具有超微孔结构，比表面积为325 m2/g。TiPW/SA在最佳反应条件下脱硫率达92．08％。
採用溶膠-凝膠法製備瞭超微孔材料（TiPW/SA ），通過FT-IR和N2吸附脫附對其進行錶徵。併以模擬汽油（二苯併噻吩硫質量分數為300 m g/kg ）氧化脫硫反應為探針反應，攷察其催化氧化吸附脫硫性能。結果錶明，TiPW/SA保持瞭Keggin結構，具有超微孔結構，比錶麵積為325 m2/g。TiPW/SA在最佳反應條件下脫硫率達92．08％。
