摘要
纳米TiO2光电催化技术,能有效减少太阳能光催化降解工业废水反应中光生电子与光生空穴的复合,提高量子利用率,从而大幅度提高光催化效率。简要介绍了纳米TiO2光电催化技术机理和应用该技术处理工业废水的技术特点;综述了二维纳米TiO2光电催化体系、三维纳米TiO2光电催化体系、分隔式纳米TiO2光电催化体系,以及矿物担载纳米TiO2光电催化体系等在国内外的研究进展;展望了纳米TiO2光电催化技术降解工业废水的应用前景。
The photo-generated charges from nano-sized TiO 2 under irradiation of solar energy can be prevented from more recombination efficiently with photoelectrocatalytic technology,and so that photocatalytic efficiency will be enhanced obviously.The mechanism and characteristics of the nano-TiO 2 photoelectrocatalytic technology are described.The development and researches of the different varieties of nano-TiO 2 photoelectrocatalytic sys-tems are reviewed and discussed,and the nano-TiO 2 photoelectrocatalytic technology will play an important roles in the treatment of industrial wastewater in the future.
