摘　　要：合成出一种新型长链锌卟啉配合物——四[3,5-二(甲氧基)-4-(十四烷基酰氧基)]苯基卟啉锌(Zn-P),将其与氧化石墨烯(GO)杂化复合,制备出一种新型的长链卟啉锌-氧化石墨烯复合材料(Zn-P/GO)。通过扫描电子显微镜(SEM)、紫外-可见吸收光谱(UVVis)、红外光谱(FT-IR)等研究,发现复合材料Zn-P与GO的结合方式为-非共价键堆积。为研究Zn-P/GO的光降解性能,选择亚甲基蓝(MB)为模型有机污染物,研究了不同光源条件下复合材料催化降解效率。A novel zinc porphyrin and graphene oxide(Zn-P/GO)composite was prepared by combining long chain tetra(3,5-dimethoxyl-4-myristoyloxy)phenyl porphyrin zinc(Zn-P)with graphene oxide(GO).The results of SEM,UV-Vis and IR shown that the binding mode of Zn-P and GO was non covalent bond-stacking.In order to study the photodegradation performance of Zn-P/GO,methylene blue(MB)was selected as the model organic pollutant to study the catalytic degradation efficiency of the composite under different light sources,and the photodegradation efficiency of Zn-P/Go and Zn-P was compared.
