摘要
采用溶剂热法,将氯化胆碱-乙二醇低共熔溶剂作反应溶剂,以二水合氯化铜(CuCl_(2)·2H_(2)O)和五水合硫代硫酸钠(Na_(2)S_(2)O_(3)·5H_(2)O)为原料合成得到了硫化铜(CuS)。采用X射线衍射仪和扫描电子显微镜对CuS进行物相与形貌表征。将不同原料配比合成的CuS作光催化剂,以亚甲基蓝(MB)为目标污染物,探究其在不同条件下对MB的光催化降解性能。结果表明:当CuCl_(2)·2H_(2)O和Na_(2)S_(2)O_(3)·5H_(2)O的摩尔比为1∶1时,制备的CuS光催化剂的催化活性最佳,对MB污染物的降解率达到70%。
CuS was synthesized via the solvothermal method using choline chloride-ethylene glycol deep eutectic solvent as the reaction medium,with copper(Ⅱ)chloride dihydrate(CuCl_(2)·2H_(2)O)and sodium thiosulfate pentahydrate(Na_(2)S_(2)O_(3)·5H_(2)O)as precursors.The phase composition and morphology of CuS were characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM).The photocatalytic degradation performance of CuS synthesized with different precursor ratios was systematically investigated using methylene blue(MB)as the target pollutant under varying experimental conditions.Results demonstrated that the CuS photocatalyst prepared at a 1:1 molar ratio of CuCl_(2)·2H_(2)O to Na_(2)S_(2)O_(3)·5H_(2)O exhibited optimal catalytic activity,achieving a degradation efficiency of 70%for MB pollutants.
