TiO_2光催化氧化水中有机污染物进展

The development of organic pollutants in water in TiO_2 photocatalytic oxidation

TiO2 —水体系在紫外光照射下 ,在TiO2 表面产生氧化能力很强的OH·自由基和超氧离子O2 - ,利用这一特性处理水中有机污染物得到很多环境工作者的密切关注。作者对TiO2 光催化的影响因素、光电催化和太阳能利用等方面的研究与应用进展作了综合评述。

When the TiO 2-water system is irradiated under the ultraviolet light, the surface of TiO 2 will produce OH· radicals and super oxide ions O 2 -. The application of this property to treat organic pollutants in water was noticed by many environmental researchers. This paper reviews the development on research and application of TiO 2 photocatalytic oxidation, including the effective factors, photoelectrocatalysis and the utilization of solar energy.
