Herein, we report the MnS, CdS and MnS/CdS nanoparticles prepared by precipitation method. The as-synthesized particles were characterized using by scanning electron microscope, X-ray diffraction, UV-diffuse reflectance spectroscopy, photoluminescence, X-ray photoelectron spectroscopy and photoelectrochemical technique. MnS/CdS composite combination enhanced the optical, photocatalytic, and photoelectronic properties of the samples. Photocatalytic performances of the samples were evaluated under visible light irradiation. The photoelectrode activity of all samples was also investigated. MnS/CdS composites were found as efficient photocatalysts under visible light. The enhanced photocatalysis of the composites was attributed to the possible defect structure, high electron density of CdS and inhibition of electron/hole pairs as well as optimal content of CdS in the composite system. MnS/CdS composites must be evaluated for photocatalytic and photoelectrochemical activities with broader visible light range.

β/γ-MnS/CdS复合光催化剂在可见光下降解氟甲喹和土霉素类抗生素的有效光催化和光电化学性能

在此，我们报告了通过沉淀法制备的 MnS、CdS 和 MnS/CdS 纳米颗粒。使用扫描电子显微镜、X 射线衍射、紫外漫反射光谱、光致发光、X 射线光电子能谱和光电化学技术对合成的颗粒进行表征。MnS/CdS 复合组合增强了样品的光学、光催化和光电性能。在可见光照射下评估样品的光催化性能。还研究了所有样品的光电极活性。MnS/CdS 复合材料被发现是可见光下的高效光催化剂。复合材料的增强光催化归因于可能的缺陷结构，CdS 的高电子密度和电子/空穴对的抑制以及复合系统中 CdS 的最佳含量。必须评估 MnS/CdS 复合材料在更宽的可见光范围内的光催化和光电化学活性。
