摘要

Titanium dioxide is undoubtedly one of the widely used and low-cost materials. Usually the TiO_2 material of which the grain size is above the micrometer scale and contains many impurities can only serve as a white pigment in paint, paper, grinding compound, toothpaste, cosmetic products, etc. Because of its semiconductivity property, TiO_2 has wide application, such as oxygen sensor, humid sensor, etc. TiO_2 is also used as good catalyst which can destroy a variety of organic dyes by means of photocatalysis decomposition, providing an efficient method for solving the problem of pollution of the organic dyes. After the pioneering work of Fujishima and Honda's in 1972, there has been increasing interest in employing this material in photoelectrochemical cell. With the rapid development in research of nano-materials recently, it was discovered that nano-TiO_2 plays a more and more important role in photocatalysis decomposition. Especially, the group led by Gratzel made an important breakthrough in photoelectrochemical solar cell by using nanocrystalline TiO_2 porous films, and they have also achieved a good result in rechargeable lithium batteries (such as Li/LCF_3SO_3+PC/TiO_2) by using nanocrystalline TiO_2 films as an electrode.
