Ag-In共掺ZnO纳米棒的性能及其应用研究

Preparation of Ag-In/ZnO nanorods on polyester fabric surface and durability finishing

以六水合硝酸锌、六亚甲基四胺、硝酸银和硝酸铟为原料,通过水热法制备出一维棒状纳米ZnO及不同掺杂比的Ag-In/ZnO复合物。样品经扫描电子显微镜、X射线衍射仪和紫外线防护系数测试仪等方法表征,结果显示:10%Ag-4%In共掺纳米ZnO于紫外光下照射120 min,水溶液中亚甲基蓝的降解率达90.17%;紫外光照180 min,亚甲基蓝几乎完全降解,故该ZnO样品具备优秀的光催化活性。改性涤纶织物经10%Ag-4%In共掺ZnO处理后,获得了国标标准下50+的紫外防护性能,即具有较好的抗紫外特性。

In this paper,rod-shaped nano ZnO and Ag/In modified ZnO composites with different doping ratio were prepared by hydrothermal method with Zn(NO3)2·6(H2O),C6H12N4,AgNO3 and In(NO3)3 as raw materials.The samples were characterized by scanning electron microscopy,X-ray diffractometry and UV protection coefficient tester.The results showed that the degradation rate of methylene blue in aqueous solution reached 90.17%when 10%Ag-4%In/ZnO was exposed to UV light for 120 min,and almost completely degraded when exposed to UV light for 180 min,showing excellent photocatalytic activity of ZnO sample.After 10%Ag-4%In/ZnO treated the modified polyester fabric,the UV shielding level was up to 50+,so it had good UV resistance property.
