摘　　要：采用凝胶-水热法,以乙酸锌和六亚甲基四胺为原料,柠檬酸为形貌控制剂于低温水热条件下在棉织物表面生长出球形纳米ZnO,并利用金属铋(Bi)、铜(Cu)对ZnO纳米球进行掺杂。采用SEM、XRD、XPS等对样品进行表征,并对负载ZnO纳米球的棉织物进行了光催化和抗紫外性能测试。结果表明:在60 min内对亚甲基蓝溶液的降解率达到99.99%,3%Bi-5%Cu掺杂的纳米ZnO棉织物的UVA和UVB分别达到2.56%和0.09%,UPF值为375.43。In this paper,spherical ZnO nanoparticles are grown on the surface of cotton fabric by gel-hydrothermal method,using zinc acetate and hmethylenetra mine as raw materials and citric acid as morphology control agent under low temperature hydrothermal condition,and then doped with bismuth(Bi)and copper(Cu):The samples are characterized by SEM,XRD and XPS,at the same time.The photocatalytic and UV resistance of the cotton fabric loaded with ZnO nanoparticles are tested.The results show that the degradation of methylene blue reaches 99.99%within 60 min.The UVA and UVB of 3%Bi-5%Cu co-doped nano-ZnO cotton fabric reach 2.56%and 0.09%,and the UPF value is exa mined to be 375.43.
