We herein report successful syntheses of both nickel cobalt sulfide (NCS) and its composite with zeolite (NCS@Z) using a solvothermal method. Techniques such as EDX analysis, SEM, and molar ratio determination were used for product characterization. The incorporation of NCS significantly changed the surface roughness and active sites of the zeolite, improving the efficiency of methylene blue degradation and its reusability, especially under UV irradiation. In comparing the pseudo-first order rates, the highest degradation efficiency of methylene blue was achieved with NCS-2@Z, having a degradation extent of 91.07% under UV irradiation. This environmentally friendly approach offers a promising solution for the remediation of methylene blue contamination in various industries.
我们在此报告了使用溶剂热法成功合成硫化镍钴(NCS)及其与沸石的复合材料(NCS@Z)。采用能谱分析(EDX分析)、扫描电子显微镜(SEM)和摩尔比测定等技术对产物进行表征。NCS的掺入显著改变了沸石的表面粗糙度和活性位点,提高了亚甲基蓝降解效率及其可重复使用性,尤其是在紫外线照射下。在比较伪一级反应速率时,NCS-2@Z对亚甲基蓝的降解效率最高,在紫外线照射下降解程度达91.07%。这种环境友好型方法为各行业亚甲基蓝污染的修复提供了一个有前景的解决方案。
