纳米TiO_2光催化降解汽车尾气技术国内研究

A dissertation on research overview on nanometer TiO_2 photocatalytic degradation automobile exhaust in China

随着我国汽车保有量的逐年上升,汽车尾气的排放危害日渐加剧,给人类的生存环境和身体健康造成了极大的威胁。纳米TiO_2光催化材料在光照条件下,能有效地分解汽车尾气中NOx、HC、CO等有害物质,改善空气质量,减少环境污染。文中论述了目前我国汽车尾气的排放状态、尾气对身体健康的危害,归纳了近年来纳米TiO_2光催化降解汽车尾气技术在我国的发展及研究现状。

As Chinese car ownership increases year by year, the emissions of automobile exhaust are increasing. In the light condition, nanometer TiO2 photocatalytic materials can effectively decompose hazardous gases including NOx, HC, CO, etc. in automobile exhaust, and improve air quality and reduce environmental pollution. The paper discusses the current state of automobile exhaust emissions, exhaust and its harm to human health, nanometer TiO2 photocatalytic degradation of automobile exhaust technology are summarized in the research status in China.
