摘　　要：介绍了以钛酸丁酯为主要原料的溶胶—凝胶法(Sol—Gel)制备TiO2光催化剂的过程,提出了较为理想的制备方法。探讨了工艺条件对催化降解效果的影响。结果表明,蜂窝陶瓷表面浸涂5层TiO2催化膜,经500℃焙烧,具有良好的光催化活性;H2O2、Fe3+、光照时间、TiO2催化膜层数对邻氯苯酚去除率有不同程度的影响。Introduced the Sol—Gel process of preparing TiO_(2) film in which butylester titanate acts as main material. And found the ideal method.Discussed the influence of photocatalysic degradation action under various technological conditions.The result indicated that TiO_(2) catalyst was in the best photocatalysic activity with 5 layers TiO_(2) film which was roasted on 500℃; the photocatalysic removal of o-chlorophenol was influenced by H_(2)O_(2)、Fe^(3+)、light application time and TiO_(2) layers.
