摘要
纳米TiO2掺杂过渡金属离子,能有效提高其光催化活性和反应效率,在处理有机废水等方面具有广阔的应用前景。综述了纳米TiO2的光催化氧化降解机理,纳米TiO2掺杂过渡金属离子的制备方法,掺杂不同金属离子对TiO2光催化性能的影响以及在多种有机废水降解方面的应用等。
The activity and photocatalyst efficiency of titanium dioxide can be enhanced obviously by transition metal dopants and it has a wide prospect on degradation of organic wastewater. The mechanism of photocatalytic degradation and the methods of preparation of transition metal-doped TiO_2 nanoparticles were described, and the kinds of transition metal dopants on the photocatalytic property of TiO_2 and the application in degradation of kinds of organic wastewater were studied.
