纳米TiO2降解汽车尾气在道路工程中的应用研究进展
Research on Nano-TiO2 Degradation of Automobile Exhaust in Road Engineering
摘要
Abstract
The degradation reaction principle of Nano-TiO2 photocatalytic material used in the process of automobile exhaust gas purification is briefly discussed in this paper.The research progress of Nano-TiO2 photocatalytic pave-ment materials is systematically sorted as well as its current applications in concrete pavements,asphalt pave-mentsand roadside facilities.Some application problems of the technology in automobile exhaust degradation are an-alyzed to propose suggestion as follows:1)Nano-TiO2 photocatalytic materials is modified to solve the problem of low catalytic efficiency;2)Porous photocatalytic material is applied to solve the problem of insufficient contact of existing road photocatalytic material with exhaust gas;3)The adhesion between the photocatalytic coating and the substrate is strengthened to solve the problem that the photocatalytic coating is easy to fall off;4)Photocatalytic products are thoroughly treated by multi measures to establish a high-quality photocatalytic system in road engi-neering.关键词
