摘要
本文研究了ＴｉＯ_２在不同制备条件下对其光催化活性的影响。结果表明，除制备方法外，加热温度和加热时间是影响ＴｉＯ_２光催化活性最主要的因素；而当两种不同晶型的锐钛矿型ＴｉＯ_２与金红石型ＴｉＯ_２以一定的比例共存时其光催化活性较好。
The influence of different preparation conditions on the photocatalytic activity of TiO_2 is studied.The results show that the preparation methods affect the photocatalytic activity of TiO2,the temperature and time of heating are the primary factors which affect the photocatalytic activity of TiO_2.The photocatalytic activity of TiO_2 is better when the anatase phase and the rutile phase coexist in a certain proportion.
