[New progress in the study on and application of organic pollutants photodegraded by nano-TiO2].

Based on the newest papers about nano-TiO2, the mechanisms of photocatalysis, ways of improving photocatalytic performance, and influencing factors of environment are discussed in this article. And the progresses in the study on some novel catalysis-enhanced or catalysis-assisted technologies such as infrared treatment, electric field effect, microwave effect and ultrasonic effect are introduced. Finally, the applications to waste water treatment, air refreshment in limited space and specially functional materials preparation in the last two years are reviewed.
