摘要: 本文综述了近些年TiO2光催化材料主要的改性方法的研究进展。TiO2光催化剂具有宽度较大的禁带、光生电子–空穴易复合等多种可修复改善的缺点，因而国内外对TiO2这类光催化剂的改性研究愈来愈多。TiO2光催化剂的改性方法主要有复合半导体、贵金属沉积、金属离子掺杂、非金属掺杂、多元共掺杂等。通过掺杂使得TiO2光催化剂将原本只响应紫外光扩大至可见光，大幅度提升TiO2光催化剂的可应用性。
Abstract: This article reviews the research progress of the main modification methods of TiO2 photocatalytic materials in recent years. TiO2 photocatalysts have various repairable and improved shortcomings, such as a wide band gap and easy recombination of photogenerated electrons and holes. Therefore, there are more and more researches on the modification of TiO2 photocatalysts at home and abroad. The modification methods of TiO2 photocatalyst mainly include compound semiconductor, precious metal deposition, metal ion doping, non-metal doping, multi-element co-doping and so on. By doping, the TiO2 photocatalyst expands its response to ultraviolet light to visible light, which greatly improves the applicability of the TiO2 photocatalyst.
