二氧化钛薄膜的制备及其光催化性能研究
|
摘要
二氧化钛(TiO2)是一种宽禁带的半导体材料,作为一种光催化剂,可以起到节约能量且保护环境资源的作用。在光照条件下,价带中的电子通过吸收光子而跃迁到导带,从而产生空穴电子对,电子可以减少空气中的氧气,空穴完全氧化并将被吸附的物质分解成小的无机分子。本文研究了二氧化钛光催化材料的发展,并分析讨论了二氧化钛薄膜光催化原理以及制备工艺。
Titanium dioxide(TiO_2) is a wide bandgap semiconductor material. As a photocatalyst,titanium dioxide(TiO_2) can save energy and protect environmental resources. Under light conditions,the electrons located in the valence band transit to the conduction band by absorbing photons,thereby generate hole-electron pairs. The electrons can reduce the oxygen in the air,and the holes completely oxidize and decompose the small molecules such as CO2 and H2 O. The investigation revealed the development of titanium dioxide photocatalytic materials,analyzed and discussed the photocatalysis principle and preparation process of titanium dioxide thin films.
