摘要
以Zn(NO3)2·6H2O和尿素为原料,通过液相沉淀法成功制备了纳米ZnO;以Cu(Ac)2、Na2S为原料,通过液相法制备出纳米CuS;将2者机械研磨制备出CuS/ZnO纳米复合材料.运用XRD、TEM和XPS对产物结构、形貌与价态等进行了表征.结果表明,样品为棒状的CuS与圆球状的ZnO结合而成,粒径在33 nm左右.通过光催化试验发现,CuS能显著地提高纳米ZnO的光催化性能.当CuS的掺杂量为0.5%时,催化效果最好.另外,CuS/ZnO纳米复合材料具有良好的光催化循环利用率.抗菌试验表明,复合物中的CuS并没有改变ZnO优异的抗菌性能.
The nano-ZnO was successfully synthesized through liquid-phase precipitation method using Zn（NO3）2·6H2O and urea as materials, and nano-CuS was prepared using Cu（Ac）2and Na2 S as materials. Then CuS/ZnO nanocomposites were obtained through mechanically grinding nano-ZnO and nano-CuS. XRD, TEM and XPS were used to characterize the structure, morphology and valence state of the product. The results showed that the product was composed of rod-like CuS and ball-like ZnO with 33 nm around particle size.The photocatalytic experimental results revealed that CuS was beneficial for the improvement of photocatalytic performance of ZnO. The catalytic efficiency of the composite reached the best when the doping density of CuS was 0.5%. In addition, CuS/ZnO nanocomposite exhibited good photocatalytic cyclic utilization rate. The antibacterial test showed that the excellent antibacterial property of ZnO was not changed by CuS addition.
