摘　　要：以纳米TiO2在混凝土道路工程中的应用为基础,以光催化反应机理为主要研究内容。从微观角度分析影响纳米TiO2光催化反应的影响因素,以提高纳米TiO2对汽车尾气分解效果,并且将其应用与透水混凝土的制备中,充分发挥两者的优势,将其应用于道路工程中,为低碳城市建设发挥更大作用。Based on application of nano-TiO2 in the concrete road engineering, this paper focuses mainly on photocatalytic reaction mechanism for low carbon-green transportation. In order to improve the decomposition of nano-TiO2 on automobile exhaust and the preparation for permeable concrete, the factor affecting micro-nano TiO2 photocatalytic reaction is studied from the view of microcosmic. The fruit will be applied to road engineering in order to play a greater role in building low-carbon city.
