Wastewater remediation is one of the special issues that have been discussed in recent years and one of the main pollutants was dyes which totally changes the water behavior. To eradicate the organic compounds from the wastewater and reuse it, there are numerous steps have been taken into consideration. Dye degradation via photocatalysis is one of the promising technique with good efficiency. Pure and tin (Sn) doped CoO was prepared employing co-precipitation technique. The structural, vibrational, optical and morphological analysis was done employing X-ray diffraction studies, Photoluminescence, Raman analysis and Scanning Electron Microscopic (SEM) studies. The well-defined nanoparticles were grown with 1 M Sn doped CoO. The photocatalytic activities of methylene blue dye under visible light were investigated by adding the samples (CS-1, CS-2, CS-3). 1 M Sn doped CoO sample showed 75% efficiency towards dye degradation. The prepared 1 M Sn doped CoO sample will be the best for photocatalytic activity. By doping Sn atoms the efficiency of the host is increased which will be the most promising candidate for the photocatalytic dye degradation applications.
废水处理是近年来讨论的一个特殊问题，主要污染物之一是染料，它完全改变了水的性质。为了从废水中去除有机化合物并重复使用废水，已经考虑了许多步骤。光催化降解染料是一种很有前途的高效技术。采用共沉淀法制备了纯钴（Sn）掺杂 CoO。通过 X 射线衍射研究、光致发光、拉曼分析和扫描电子显微镜（SEM）研究进行了结构、振动、光学和形态分析。在 1 M Sn 掺杂 CoO 中生长了具有良好定义的纳米粒子。通过添加样品（CS-1、CS-2、CS-3）研究了亚甲基蓝染料在可见光下的光催化活性。1 M Sn 掺杂 CoO 样品对染料降解的效率达到 75%。所制备的 1 M Sn 掺杂 CoO 样品将具有最佳的光催化活性。通过掺杂 Sn 原子，提高了宿主的效率，这将是光催化染料降解应用最有前途的候选材料。
