摘　　要：以六水合硝酸锌、三水合硝酸铜、六水合硝酸镍为原料,通过水热法制备了不同含量铜镍共掺杂的ZnO纳米光催化材料,并利用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、紫外分光光度计(UV-Vis)等测试技术对制备出的样品进行表征与分析。通过模拟测试光催化降解废水染料中罗丹明B效率来考察铜镍掺杂ZnO的光催化活性。研究结果表明,制备出的铜镍掺杂ZnO呈现典型的六方纤锌矿构型,由不规则纳米颗粒组成。铜镍共掺杂的ZnO光催化活性最好,明显好于纯ZnO和单掺杂ZnO,在10W紫外灯照射5h后,对罗丹明B的光催化降解率可达91.92%。A series of ZnO nanocomposite doped with different amounts of Cu and Ni were prepared by hydrothermal method with Zn(NO_(3))_(2)·6 H_(2)O and Cu(NO_(3))_(2)·3H_(2)O and Ni(NO_(3))_(2)·6H_(2)O as raw materials.The prepared samples were characterized and analyzed by X-ray diffractometer(XRD),scanning electron microscope(SEM),and ultraviolet and visible spectrophotometry(UV-Vis).The photocatalytic activity of(Cu,Ni)-codoped ZnO nanocomposite was investigated by simulating the efficiency of photocatalytic degradation of rhodamine B in dyes wastewater.The research results showed that the Cu/Ni-doped ZnO nanocomposite presented a typical hexagonal wurtzite configuration,the morphology was irregular nanoparticles.The photocatalytic activity of(Cu,Ni)-codoped ZnO nanocomposite was the best,which was significantly better than pure ZnO and single-doped ZnO,after irradiating with a 10 W ultraviolet lamp for 5 h,The photodegradation of rhodamine reached 91.92%.
