摘要: 设计合成一种巴豆酰氧基取代的锌卟啉(TMPTPPZn)配合物, 将其与甲基丙烯酸甲酯(MMA)进行共聚反应, 得到锌卟啉-聚甲基丙烯酸甲酯(PMMA)共聚物(TMPTPPZn-PMMA),再以聚丙烯腈(PAN)为纺丝液, 利用静电纺丝技术制备负载TMPTPPZn-PMMA和AgX(X=Cl,Br,I)的复合纤维TMPTPPZn-PMMA/AgX/PAN, 利用扫描电镜(SEM)研究复合纤维的形貌, 利用热重分析(TGA)研究复合纤维的热稳定性, 并研究其对有机染料降解的催化活性. 结果表明: TMPTPPZn-PMMA/AgCl/PAN,TMPTPPZn-PMMA/AgBr/PAN和TMPTPPZn-PMMA/AgI/PAN均具有较高的光催化活性, 能有效催化降解废水中的有机染料; 可见光照射240 min后, 3种复合纤维对亚甲基蓝降解率分别为96.02%,94.75%和90.91%, 对罗丹明B的降解率分别为93.40%,94.71%和96.54%.

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.
