The present work focuses on the synthesis of pure SnS₂ nanopowder, pure CdO nanopowder and SnS₂-CdO nanocomposite by a cost effective chemical method using tin (II) chloride, thiourea and cadmium acetate as the precursor salts. The synthesized samples were characterized by using X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Energy dispersive X-ray spectroscopy(EDS), Transmission Electron Microscopy (TEM), X-ray Photoelectron Spectroscopy (XPS), Fourier Transmission Infrared Spectroscopy (FTIR), UV–Vis diffuse reflectance spectroscopy, Photoluminescence (PL) Spectroscopy and Electron spin resonance (ESR). Diffraction peaks related to both SnS₂ and CdO was observed in the XRD pattern of the composite. Photocatalytic studies established that the composite exhibit a photodegradation efficiency of nearly equal to 86.11% against rhodamine B and 92.86% against congo red dyes. Also, the SnS₂-CdO nanocomposite exhibited enhanced photocatalytic H₂ evolution activity, from visible light water splitting.

目前的工作集中在通过使用氯化锡（II），硫脲和乙酸镉作为前体盐的经济有效的化学方法合成纯SnS ₂纳米粉，纯CdO纳米粉和SnS ₂ -CdO纳米复合材料。合成的样品通过X射线衍射（XRD），扫描电子显微镜（SEM），能量色散X射线光谱（EDS），透射电子显微镜（TEM），X射线光电子光谱（XPS），傅里叶透射进行表征红外光谱（FTIR），紫外可见漫反射光谱，光致发光（PL）光谱和电子自旋共振（ESR）。与两个SnS ₂相关的衍射峰在复合材料的XRD图中观察到CdO。光催化研究表明，该复合物对罗丹明B的光降解效率接近86.11％，对刚果红染料的光降解效率为92.86％。而且，SnS ₂ -CdO纳米复合材料由于可见光水分解而显示出增强的光催化H ₂放出活性。
