摘　　要：用溶胶-凝胶法在玻璃表面制备了负载型纳米TiO2光催化剂,在自然光(太阳光)条件下,考察其光催化活性.结果表明,在450℃焙烧1 h制备的光催化剂,具有完整的锐钛矿相,粒径约为18 nm.对甲基蓝溶液的光催化活性高于DegussaP25,且稳定性较好,可重复使用.The photocatalyst of TiO2 thin films were prepared on the sodium glass by sol-gel method, the degradation of methyl blueness by photocatalysis was studied using the in sunlight as lamp-hour. The results show that the film has good anatase crystals when it was annealed at 450℃ for lh., and the size is about 18 nanometer. The study of degmdating the slountion of methyl blueness shows that the photo,activity of the film is better than that of DegussaP25, and has good stability, the film has the value of practical application.
