摘要

采用溶剂热法制备出含Ti³⁺自掺杂的黑色TiO₂薄膜,采用X射线衍射、扫描电镜、紫外可见漫反射吸收光谱、拉曼光谱和X射线光电子能谱等手段对其进行了表征。光催化结果显示,黑色TiO₂薄膜的可见光催化活性高于白色TiO₂薄膜,对罗丹明B的降解速率提高了约18%。其优越的可见光催化活性归因于表面的无定形TiO₂和较高的Ti³⁺含量。

Abstract

The self-doped black TiO₂ film containing Ti³⁺ was prepared by solvothermal method,and characterized by XRD,SEM,UV-Vis,Raman and XPS.The photocatalytic results showed that the visible light catalytic activity of the film was higher than that of white TiO₂ film,and the degradation rate of Rhodamine B was increased by 18%.Its superior visible light catalytic activity was attributed to amorphous TiO₂ and high Ti³⁺ content on the surface.
