Abstract The heterostructured ternary Cd/CdS/BiOCl photocatalysts were synthesized in a simple way and they exhibited a superior photocatalytic activity toward photodegradation of RhB. The Cd/CdS/BiOCl photocatalysts were characterized by Diffused reflectance spectroscopy (DRS), X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM). These analysis methods revealed a chemical interaction between Cd/CdS and BiOCl resulting in the formation of heterojunction. The CCB-3 sample showed high durability and photocatalytic activity for RhB degradation ratio of 90% after 4 runs under visible light irradiation. This work assembled Z-scheme Cd/CdS/BiOCl photocatalysts which had potential future applications in improving environment.

用于增强可见光光催化降解废水中有机污染物的异质结构三元 Cd/CdS/BiOCl 光催化剂的制备

摘要 以简单的方法合成了异质结构的 Cd/CdS/BiOCl 三元光催化剂，它们对 RhB 的光降解表现出优异的光催化活性。Cd/CdS/BiOCl 光催化剂通过漫反射光谱 (DRS)、X 射线衍射 (XRD)、透射电子显微镜 (TEM)、X 射线光电子能谱 (XPS)、扫描电子显微镜 (SEM) 进行表征。这些分析方法揭示了 Cd/CdS 和 BiOCl 之间的化学相互作用，导致异质结的形成。CCB-3 样品在可见光照射下运行 4 次后，RhB 降解率为 90%，显示出高耐久性和光催化活性。这项工作组装了 Z 型 Cd/CdS/BiOCl 光催化剂，在改善环境方面具有潜在的未来应用。
