摘　　要：综述了近年来具有光催化活性的纳米二氧化钛颗粒及薄膜的低温制备研究新进展，按水热法、溶胶-凝胶法及沉淀法分类介绍了纳米二氧化钛的低温制备的反应原理、产物性能及优缺点，评述了二氧化钛在高分子材质上的负载化研究进展，并展望了该领域的研究前景。The recent developments in the preparation of the photocatalytical titania nanoparticles and thin films at low temperature were reviewed. The reaction mechanisms, properties of the products, and their （dis）advantages were compared for the different preparation methods, such as hydrothermal methods, sol-gel methods, precipitation process at low temperatures, and so on. The depositions of nano-titania thin films on the materials of polymers were discussed. The prospects in this field are mentioned.
