摘要
随着我国生态文明战略的推进,汽车尾气的治理受到了广泛关注。TiO_(2)被认为是极具开发前景的光催化材料,研究其改性方法,有助于发挥其在尾气净化方面具有的优势。本文简要论述了尾气对人体的危害,尾气的主要治理措施,介绍了光催化技术的发展历程,光催化降解尾气的反应机理,总结了国内外纳米光催化技术在治理汽车尾气方面的应用现状,最后归纳了纳米光催化中存在一些问题,并对该技术提出展望。
With the development of China s ecological civilization strategy,the management of automobile exhaust gas has been widely concerned.The nano-TiO_(2 )is considered to be a promising photo catalytic material,and the study of its modified methods can help to take advantage of its advantages in exhaust gas purification.The harm of exhaust gas to human body and the main management measures of exhaust gas were briefly discussed,the development course of photocatalytic technology and the reaction mechanism of photocatalytic degradation exhaust gas were introduced,the application status of nano-photocatalytic technology at home and abroad in the treatment of automobile exhaust gas was summarized,and some problems in nano-photocatalysis were finally summarized,and the prospect of the technology was put forward.
