负载锌卟啉和AgX纳米粒子复合纤维的制备及其光催化降解有机染料
Preparation of Composite Fibers Loaded with Zinc Porphyrin and AgX Nanoparticles and Their Photocatalytic Degradation of Organic Dyes
摘要
Abstract
We designed and synthesized a crotonyloxy-substituted zinc porphyrin(TMPTPPZn)complex,which was copolymerized with methyl methacrylate(MMA)to obtain a zinc porphyrin/polymethyl methacrylate(PMMA)copolymer(TMPTPPZn-PMMA).Then using polyacrylonitrile(PAN)as the spinning solution,we prepared composite fibers TMPTPPZn-PMMA/AgX/PAN loaded with TMPTPPZn-PMMA and AgX(X=Cl,Br,I)by using electrospinning technology.The morphology of the composite fibers was studied by scanning electron microscopy(SEM),the thermal stability of the composite fibers was studied by using thermogravimetric analysis(TGA),and studying their catalytic activity for the degradation of organic dyes.The results show that the TMPTPPZn-PMMA/AgCl/PAN,TMPTPPZn-PMMA/AgBr/PAN and TMPTPPZn-PMMA/AgI/PAN all have high photocatalytic activity and can effectively catalyze the degradation of organic dyes in wastewater.After 240 min of visible light irradiation,the degradation rates of methylene blue(MB)by the three composite fibers are 96.02％,94.75％and 90.91％,and the degradation rates of rhodamine B(RhB)are 93.40％,94.71％and 96.54％,respectively.关键词
