摘要
概述了TiO2光催化氧化降解水中污染物的原理及TiO2光催化剂的制备,提出了增强其活性的途径。TiO2光催化氧化可应用于印染、农药、造纸等工业废水及饮用水处理中,研制高效的负载型纳米TiO2光催化剂、解决太阳能利用问题、开发多功能光催化反应器是今后TiO2光催化氧化的发展趋势。
Photocatalytic oxidation principle of pollutant degradation with TiO2 and the preparation of TiO2 are illustrated, the approaches to improve its activity are discussed. TiO2 photocatalytic technology can be applied to the treatment of industrial wastewater and drinking water. Development tendency of the technique in recent years is the developing efficient loading TiO2 photocatalyst, solving the problem of solar energy utilization and developing multifunctional photocatalvtic reactor are the the main tendency in future.
