纳米二氧化钛的性质及应用进展

纳米二氧化钛微粒具有大的比表面积,其表面原子数、表面能和表面张力随粒径的下降急剧增加,由于其尺寸的细微化,表现出来独特的物理和化学特性,导致纳米二氧化钛微粒的热、光、敏感特性和表面稳定性等方面不同于常规粒子,这就使得它在环境、信息、材料、能源、医疗与卫生等领域有着广阔的应用前景。综述了纳米二氧化钛的性质,并介绍了近年来纳米二氧化钛的应用研究发展动态。

Progress in the Application and Properties of Nano- titania

Because special physics and chemistry properties of nano- titania particles such as heat, light, sensitive properties and surface stability were quite different from general materials, they were intensively applied in the environment, information, material, sources of energy, medical treatment and hygiene etc. The surface atom number, surface ability and surface tension of nano - titania particles with high surface area were sharply increased along with the digression of the diameter. The properties of nano- titania were summarized, and the progress in the application of nano- titania in recent years was described.
