高稳定性、高光催化活性的锐钛矿TiO_2的制备

Synthesis of high stability anatase TiO_2 with high photocatalytic activity

本文采用溶剂热路线和乙二胺回流后处理的方法制备了高温稳定性的纯锐钛矿TiO2。结果表明该方法制备的锐钛矿纳米TiO2具有小晶粒尺寸、大比表面积和高结晶度的性质,并且表现出极高的光催化活性,其活性超过了国际上公认的Degussa P25。

In this paper,high stability anatase TiO2 was prepared via solvthermal route and followed EN treatment.The results showed that the prepared TiO2 possessed the characteristic of small particle size,large surface area and high crystallinity.The photocatalytic activity of the prepared TiO2 was also superior to that of commercial Degussa P25.
