将纳米二氧化钛应用于客车车厢内有机毒物的分解。研究表明，在紫外光照射下，纳米二氧化钛对车内主要有机污染物甲苯、二甲苯、甲醛和总有机挥发物的降解率分别达到93．8％、91．6％、64．8％和88.3％。参照国家室内空气质量标准，在对车内空气污染物进行了治理后，甲苯、二甲苯和总有机挥发物分别达到了国家标准，甲醛的含量也大幅度下降。数据表明，光催化法可以用作车内空气污染的治理。

This paper studies the degradation of organic pollutants in vehicles by the nano-titania photocatalyst. The results show that the photocatalyst can effectively decompose the pollutants in vehicles under ultraviolet light. The degradation ratios of toluene, dimethylbenzene, formaldehyde and the total value of organic compounds are 93.8% ,91.6% ,64.8% and 88.3% respectively. After the photocatalysis is conducted,the content of toluene, dimethylbenzene and the total value of organic compounds in vehicle is lower than the safe values by the state standard of indoor healthy air quality. The amount of formaldehyde also decreases obviously after the photocatalysis. Thus, the photocatalysis can be used to degrade organic pollutants in vehicles.
