摘要: 以钛酸丁酯和葡萄糖为原料用水热法制备了碳掺杂二氧化钛, 再进一步对其进行Ag@AgCl表面修饰.用X射线衍射(XRD), X射线光电子能谱(XPS), 透射电镜(TEM), BET比表面仪和紫外-可见(UV-Vis)漫反射光谱等手段对样品进行测试表征; 在可见光辐射下(λ>420 nm), 以甲基橙和苯酚溶液的光催化降解实验来评价样品的活性. 结果表明: 经Ag@AgCl修饰后, 样品的粒径增大, 比表面积减小, 对可见光的响应增强; 可见光光催化效率有大幅度提高, 对甲基橙和苯酚的降解效率分别是修饰前的5.5 和3.4 倍, 且光催化剂经三次循环使用后活性基本保持不变.

Abstract: C-doped TiO₂ was prepared from butyl titanate and glucose by a hydrothermal method. The prepared C-doped TiO₂ was further modified with Ag@AgCl. The obtained samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), BET surface area analysis, and UV-Vis diffuse reflectance spectroscopy. The photocatalytic activity of the samples was evaluated by the degradation of methyl orange and phenol under the visible light irradiation (λ >420 nm). After modification with Ag@AgCl, the C-doped TiO₂ samples had a larger particle size and smaller surface area with enhanced response to visible light and greatly improved visible-light photocatalytic activity. The degradation rates of methyl orange and phenol over Ag@AgCl/TiO_2-xC_x were 5.5 and 3.4 times as large as those over TiO_2-xC_x, respectively. The photocatalytic activity of Ag@AgCl/TiO_2-xC_x under visible light remained almost unchanged after three cycles.
