摘要:

TiO2光催化納米粒子因其具有捕捉和分解空氣污染物的能力，廣泛作為清潔功能型材料應(yīng)用于路面中，前景可觀。本文在近幾年國內(nèi)外研究基礎(chǔ)上，對納米TiO2應(yīng)用于路面降解汽車尾氣的研究，進行了系統(tǒng)的敘述。首先介紹了納米TiO2光催化降解汽車尾氣的作用機理；其次對納米TiO2的改性理論和改性效果進行總結(jié)和論述；然后介紹了納米TiO2降解NOX的研究情況和納米TiO2路面的路用性能；最后對目前該領(lǐng)域的一些問題進行探討，并展望了納米TiO2應(yīng)用于路面降解汽車尾氣的發(fā)展趨勢。

Abstract:

The TiO2 photocatalytic nanoparticles have been widely used in pavement as cleaning function materials due to the ability of catching and resolving the air pollutant, which have an excellent prospect. This paper summarizes the application research of nano TiO2 on pavement for the degradation of vehicle exhaust on the basic of domestic and foreign research in recent years. Firstly, the photocatalytic degradation mechanism of vehicle exhaust by nano TiO2 was introduced. Secondly, the modification mechanism and the modification effect of nano TiO2 were summarized and discussed. Moreover, the studies on the degradation of NOx by nano TiO2 were introduced, the degradation performance of tail gas and pavement performance of pavement containing nano TiO2 were analyzed. Finally, some problems in this field were discussed, and the development trend and the application prospect of nano TiO2 on pavement for the degradation of vehicle exhaust were prospected.
