摘　　要：TiO2薄膜的光催化性能研究前景广阔,具有纳米结构特征(如晶粒尺寸纳米化,大比表面积,高孔隙度等)的TiO2薄膜的光催化活性明显改善。文中主要探讨了TiO2薄膜的光催化性能,介绍了晶型、比表面积、粒径等形态结构以及金属离子掺杂、半导体耦合、贵金属沉积、光敏化等多种改进技术对其光催化性能的影响,及其研究进展情况。The study on TiO_2 film as a photo- catalyzer has an attractive application perspective. It is generally agreed that TiO_2 films with a nano-crystal and micro-pore structure shows good photo-catalytic performances. The article introduces the photo-catalytic mechanism of TiO_2 and discusses the influence of different factors and techniques on the photo-catalytic properties. These factors include the morphological structure such as a crystal structure, surface area and particle size; and the techniques are about the metal ion adulteration, precious metal deposition, composite semiconductors, photosensitization and so on. Recent studies on the photo-catalytic performance of nano-crystal TiO_2 films are briefly reviewed.
