摘　　要：光催化氧化法是如今新型的污水处理方法,而二氧化钛在光催化氧化法中发挥着很重要的作用。本文对二氧化钛的晶体结构进行了研究,从而找出二氧化钛因结构具有较高的光催化活性,良好的亲水性,较好的热稳定性能,无毒无二次污染等独特的性质,使其作为半导体在光催化氧化法中起重要的作用。最终达到处理污水的目的。Photocatalytic oxidation is a new type of sewage treatment, and Titanium dioxide plays an important role in thephotocatalytic oxidation. In this paper, the crystal structure of titanium dioxide was studied, so as to find the titanium dioxidebecause of the structure has a high photocatalytic activity, good hydrophilieity, good thermal stability, non -toxic secondarypollution and other unique properties ,titanium dioxide as a semiconductor in the photocatalytic oxidation which plays an importantrole. Finally achieve the purpose of sewage treatment.
