摘要
光催化技术已成为当前环保领域的研究热点之一,TiO_2作为目前最有前景的光催化材料,已经广泛运用于城市建筑领域,但在水工行业尚无应用。对TiO_2光催化氧化和光致超亲水性机理,及其在空气污染物净化、除菌、自清洁和防雾材料等方面的研究与应用做了综述。并结合光催化技术对大坝混凝土表面耐污性耐候性问题的解决做了展望。
The photocatalytic technology has become one of the research focuses in the field of environmental protection. As the most promising photocatalytic material, TiO 2 has been widely used in urban construction, but yet in hydraulic engineering industry. In this paper, the TiO 2 material is introduced, including the photocatalytic oxidation and photo-induced super-hydrophilicity mechanisms, and the applications in air pollutant purification, sterilization, self-cleaning and anti-fogging. Also, the application prospect of the photocatalytic technology in dam concrete for the surficial stain resistance and weatherability is discussed.
