摘要：纳米钛白的制备方法大致可分为两类,即气相法和液相法,而液相法是研究的重点和热点。目前已经发现纳米钛白在催化及环境保护方面有广泛的应用前景,已经形成了相关的产业,并有可能成为本世纪利用太阳能净化环境的又一次技术革命。纳米钛白的分散性问题依然是未来相当一段时间内急待解决的技术核心,这也是纳米钛白研究的关键技术之一。另外纳米钛白在环保、塑料、涂料等相关领域中的应用技术的开发同样具有重大意义。

Abstract: There are mainly two methods to prepare nano-sized titania.The liquid-phaseuch as vapor-phase process and liquid-phase process.rocess is the key process and is studied the most. Now it has been foundapplications ofnano-titania in catalysis and protection ofmanyenvironment. And it has formed new related industry in the application ofnano-titania. It may lead to a new revolutionary in using of solar energy.The dispersion of nano-sized titania is one of the most important tasks tobe solved out in the near future. At the same time, the application study ofnano-tatinia in environment, plastic and paint are also very important.
