| 摘 要： | 采用钛酸丁酯的溶胶-凝胶法及微波干燥制备了纳米TiO2光催化剂。通过XRD和BET进行了晶型、平均粒径和比表面积分析表征。以水杨酸为模拟污染物对其进行光催化降解活性实验研究表明，UV光照40min水杨酸降解率达到97％，催化剂重复使用4次水杨酸降解率仍能达到94％。

| Abstract: | The nanocrystalline TiO_2 photocatalysts were prepared by means of the Sol-Gel method and microwave drying from Ti(OBu)4,and the crystal type,the average size and the specific surface area were characterized by means of XRD and BET.The experimental results of the photocatalytic degradating sulfosalicylic acid indicated that the degradating ratio of sulfosalicylic acid was 97% by the UV rays irradiation in 40 min,and the degradating ratio of sulfosalicylic acid was 94% on the photocatalyst used repeatedly 4 times. |
