摘要 以氯化铜(CuCl2·2H2O)和硫粉(S)为原料,乙醇(C2H6O)和水的混合液为溶剂,于180℃下反应24h成功制备了几种形貌的Cu7S4/CuO半导体复合材料。分别用X射线粉末衍射仪、扫描电子显微镜、紫外-可见分光光谱仪等手段对产品进行了表征,采用氙灯模拟太阳光,探讨了Cu7S4/CuO半导复合材料对有机染料罗丹明B溶液的降解效果。结果表明,水热法合成的产物结晶性良好,随着用水量的减少,形貌由颗粒状转变为微纳米线状;光催化降解实验显示,微纳米线状的Cu7S4/CuO复合材料具有更好的催化性能,在20min内对罗丹明B的降解率达到95%以上。

Abstract: Using copper chloride (CuCl2·2H2O) and sulfur powder (S) as raw materials,and a mixture of ethanol (C2H6O) and water as solvent,a semiconductor composite composed of several morphologies of Cu7S4 and CuO was successfully prepared by reaction at 180℃ for 24 hours.The products were characterized by XRD,SEM and EDS.The xenon lamp was used to simulate sunlight to investigate the degradation effect of Cu7S4/CuO semiconductor composites on rhodamine B solution.The results shown that the products synthesized by the hydrothermal method had good crystallinity.With the decrease of water consumption,the morphology changed from granular to micro-nanowires.Photocatalytic degradation experiments shown that the micro-nano-wire Cu7S4/CuO composites had better catalytic performance,the degradation rate of rhodamine B was more than 95% in 20 minutes.
