摘　　要：二氧化钛作为光催化材料,具有高稳定性、高活性、低成本、环境友好等优点。但是,二氧化钛在可见光区的吸收受限,并且由于载流子复合速率过快,其催化速率较低。为此,本文研究了二氧化钛的改性方法,讨论不同改性方法对二氧化钛结构和性能的影响。同时,为进一步提高二氧化钛的催化性能探讨了不同因素对光催化反应的影响。As a photocatalyst material,titanium dioxide has the advantages of high stability,high activity,low cost and environmental friendliness.However,the absorption of titanium dioxide in the visible light region is limited,and its catalytic rate is low due to the carrier recombination rate is too fast.Therefore,this paper studies the modification methods of titanium dioxide,and discusses the influence of different modification methods on the structure and properties of titanium dioxide.At the same time,in order to further improve the catalytic performance of titanium dioxide,the influence of different factors on the photocatalytic reaction was discussed.
