Selective doping has been proved to be a semiconductor oxide improve the photocatalytic activity of the most effective ways The introduction of certain metal ions can greatly improve the photocatalytic oxidation efficiency, Recently, a lot on the adoption of the doping to improve the photocatalytic oxidation performance reports, doped semiconductor photocatalysis material because of its physical and optical properties change, thereby improving the photocatalytic properties.

有选择性的进行掺杂已被证明是一种提高半导体氧化物光催化活性的极其有效的方法，掺入一定的金属阳离子能极大的提高TiO2的光催化效率，最近有大量的关于通过掺杂来提高TiO2的光催化性能的报道，掺杂的半导体光催化材料由于其物理和光学性质的改变，通过扩展光响应范围和提高光生电荷的分，从而提高了光催化性能。
