摘　　要：为研究纳米二氧化钛光催化剂的抗菌作用,综述了国内外通过在纳米二氧化钛中掺杂阴、阳离子和复合半导体等方式来提高纳米二氧化钛的光催化活性和在可见光下的杀菌效率等方面的研究进展,然后介绍了纳米二氧化钛在陶瓷、玻璃、不锈钢、塑料、涂料以及其他方面的抗菌作用,指出纳米二氧化钛的晶态结构、表面结构、能带结构等因素对其光催化活性的影响以及光催化的反应机理的研究是今后需要着重研究的。The recent progresses of nano-TiO2 photoeatalyst such as improvement of its photocatalytic activity and antibacterial activity ander the visible light condition hy doping anions, ions or eomposing semieondactors were reviewed to study the antibacterial properties of nano-TiO2. The antihacterial applications of nano-TiO2 in ceramic, glass, stainless steel, plastics, coating and so on were intmdaced. The farther research topics of the effects of crystal structure, surface Struture. energy band structure on the photocatalytic activity and the reaction mechanism of photocatalysis were suggested.
