In this study, Ag/AgCl photocatalysts were prepared by using chloride ionic liquid (IL) as a chlorine source. The structure, composition, morphology, light response ability and surface properties of IL-AgCl were characterized by X-ray diffraction, scanning electron microscope, X-ray photoelectron spectroscopy, Raman spectroscopy, UV–Vis diffuse reflection spectra, specific surface area and surface photovoltage spectrum. The photocatalytic activity of the samples was investigated by measuring the residual concentration of rhodamine B used as a simulated pollutant. The experimental results show that the ionic liquid can promote the stability of AgCl, furthermore, all the IL-AgCl photocatalysts have a higher separation rate of photogenerated charge pairs than the reference AgCl. The surface properties and photocatalytic activity of AgCl prepared tightly relate to the type of IL used, among all the AgCl prepared, AgCl prepared by 1-carboxyethyl-3-methyl-imidazolium chloride has the best catalytic activity.

以离子液体为氯源制备具有增强光催化活性的AgCl

在本研究中，以氯化物离子液体 (IL) 作为氯源制备了 Ag/AgCl 光催化剂。通过X射线衍射、扫描电子显微镜、X射线光电子能谱、拉曼光谱、UV-Vis漫反射光谱、比表面积和表面特性对IL-AgCl的结构、组成、形貌、光响应能力和表面性质进行了表征。光电压谱。通过测量用作模拟污染物的罗丹明 B 的残留浓度来研究样品的光催化活性。实验结果表明，离子液体可以促进 AgCl 的稳定性，而且所有 IL-AgCl 光催化剂都比参比 AgCl 具有更高的光生电荷对分离率。
