Progress of Nano-TiO_2 Research

纳米TiO2具有诸多优良特性,有着极好的应用前景。特别是在光催化领域,纳米TiO2的光催化作用可以把光能转变为电能和化学能,实现许多通常情况下难以实现或不可能进行的反应;用于环境治理,它的分散性以及对紫外线较好的屏蔽作用,使其广泛用于制备化妆品、防护漆等;此外,纳米TiO2还可作为吸收、反射红外光、隐身、静电屏蔽和增强增韧等材料。文章综述了纳米TiO2的特性、主要制备方法和主要应用领域,并结合实际应用中存在的问题,对纳米TiO2的发展趋势作出展望。

Nano -TiO2 has many good features and excellent prospects of application. Especially in the field of photocatalytic, nano - TiO2 photocatalysis in solar energy can be transformed into electrical energy and chemical energy, which can achieve a number of difficult or impossible reactions in normal ways. For environmental control, its dispersion and good ultraviolet shielding effect are widely used in preparation of cosmetics, protective paint, etc. In addition, nano - Ti02 can also serve as material for absorption, reflection of infrared light, invisibility, electrostatic shielding and tough enhancement. This paper gives an overview on the characteristics of nano - TiO2, main preparing methods, major application areas, and the existing problems in practical application, the development of nano - TiO2.
