氧化锌和硫化镉共复合氧化亚铜纳米线的制备及其光催化性质

Preparation and photocatalytic properties of cuprous oxide nanowires co-composite with zinc oxide and cadmium sulfide

以氯化铜和氢氧化钠为原料,聚乙二醇为表面活性剂,水合肼为还原剂,水为溶剂,采用简单还原法制备氧化亚铜纳米线。然后通过水热法将纳米氧化亚铜、氧化锌和硫化镉进行复合。利用SEM和XRD对制备的产品进行表征。对制备的产品进行光催化活性测试。结果表明,在以汞灯为光源,亚甲基蓝的浓度为15 mg/L时,三元复合的产品活性最高,单纯氧化亚铜纳米线活性最低。

Copper oxide nanowires were prepared by simple reduction method using copper chloride and sodium hydroxide as raw materials,polyethylene glycol as surfactant,hydrazine hydrate as reducing agent and water as solvent.Then nano-cuprous oxide,zinc oxide and cadmium sulfide were compounded by hydrothermal method.The product was characterized by SEM and XRD.The photocatalytic activity of the prepared product was tested.The results show that when the mercury lamp is used as light source and the concentration of methylene blue is 15 mg/L,the activity of the ternary composite is the highest and the activity of pure cuprous oxide nanowires is the lowest.
