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.
