摘　　要：采用高压静电纺丝技术,制备出一种具有微纳米尺寸结构并含羧基的电纺纤维。120℃水热条件下负载PbS-ZnS异质结形成PbS-ZnS/电纺纤维复合材料,利用SEM、XRD、XPS、TGA、UV-Vis等多种分析测试方法进行表征,证明PbS-ZnS异质结能均匀分布在电纺纤维上。用汞灯模拟在紫外光源研究复合材料的光催化降解性能,以甲基橙为目标污染物进行研究,结果表明,复合材料具有较好的有机物降解能力,光降解300 min甲基橙的残余质量为1.23%。Carboxyl electrospinning fiber with micro and nano size was prepared with electrospinning technology. PbS-ZnS heterojunction was loaded on carboxyl electrospinning fibers under hydrothermal conditions at 120 ℃. The PbS-ZnS electrospinning fiber composites were characterized by SEM, XRD, XPS, TGA, UV-Vis and so on. The PbS-ZnS heterojunction was uniformly dispersed on electrospinning fibers. It was found that the composites exhibited the best photocatalytic efficiency in the degradation of methy orange aqueous solution with a degradation rate of 1.23 %.
