摘　　要：针对近年来纳米TiO2研究的新成果,综述了纳米TiO2制备的研究进展;对影响纳米TiO2光催化降解的因素(如纳米TiO2的晶型与粒径、掺杂与改性及辅助光催化技术等)进行了讨论;对纳米TiO2在环境保护领域的主要应用进行了评述。指出纳米TiO2光催化技术尚未完全达到实际应用水平,还存在一些明显的不足,将纳米TiO2光催化技术和传统水处理技术相结合可能是一个很好的发展方向。In recent years, study on preparation and application of nano - titania material has developed rapidly. Besides a brief survey of recent research advances on preparation of nano - titania, discussion of influencing factors on photocatalytic degradation, such as the crystal type and particle diameter, doping and modification, auxiliary photocatalytic technique used in degradation etc. were focused on. In addition, main applications of nano - titania in environmental protection field were also reviewed. Although technology of using nano - titania as photocatalyst has some obvious disadvantages and has not been fully applied in actual treatment process of environmental pollutants, but to combine photocatalytic activity of nano - titania with the traditional water treatment techniques maybe is a promising task to be worked on.
