摘要/Abstract

摘要：

以乙醇为碳源，采用操作简单的真空活化法一步实现对TiO₂的Ti³⁺与C的共掺杂改性，TiO₂用X衍线衍射、紫外-可见光谱、顺磁共振、X射线光电子能谱和红外光谱等手段表征了催化剂的结构、组成、光学性质. 结果表明，经Ti³⁺与C共掺杂改性后的催化剂表现出高的可见光降解甲基橙活性. 复合在催化剂表面的石墨可以增强催化剂对可见光的响应范围，而Ti³⁺与氧缺陷形成的掺杂能级则可以提高光生电子的迁移效率. 实验表明，两者之间的协同作用促进了其可见光催化活性的提高.

Abstract:

Using ethanol as the carbon source, a series of Ti³⁺ and carbon co-doped TiO₂ samples were successfully synthesized by an innovative and simple vacuum activation method in a one-step process. The Ti³⁺ self-doped TiO₂ featured a high visible light photocatalytic activity that improved considerably following subsequent carbon doping modification of the catalyst surface. The samples were characterized by X-ray diffraction, UV-Vis diffuse reflectance spectroscopy, electron spin resonance, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The Ti³⁺ and C co-doped TiO₂ catalyst showed a high methyl orange photo-degradation efficiency under visible light irradiation. The doping levels induced by Ti³⁺ and oxygen vacancies were responsible for the improved visible light response of TiO₂. Simultaneously, the surface coverage of graphite on the catalyst could improve the absorption of visible light and migration efficiency of photo-induced electrons. The synergistic effects of Ti³⁺ self-doping and graphite coverage led to the improved visible light photocatalytic activity of Ti³⁺ and C co-doped TiO₂.
