摘　　要：二氧化钛是一种重要的光催化剂,在环保、清洁能源等领域都有很高的应用价值,但较宽的禁带使其不能得到广泛的应用,因此对它进行掺杂改性,使其能吸收可见光,提高光催化效率至关重要。综述了硫掺杂对二氧化钛改性的机理,总结了掺杂对二氧化钛的晶体结构、电子结构及光学性质的影响,并指出了硫掺杂二氧化钛研究中存在的主要问题。Titanium dioxide is a very important photocatalyst and has a significant application potential in envi ronmental protection, clean energy field, etc. However, the application has been limited for its wide band-gap. It is crucial to have TiCh modified and make it absorb visible light and improve the photocatalytic activity. The modified mechanism of Ti02 doped with sulfur is introduced, the effects of sulfur doping on the crystal, optical properties and electrical structure are summarized, and the problems are also indicated.
