摘　　要：借助超声辅助复合的方式,制备了四-β-(对硝基苯氧基)酞菁钴/酸化多壁碳纳米管复合材料(TNPPcCo/aMWCNT)。采用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X-射线光电子能谱仪(XPS)等多种手段对TNPPcCo/aMWCNT进行了表征。结果表明,TNPPcCo独特的周边取代基增强了其与aMWCNT间的π-π作用,促进了两者的复合,从而提高了TNPPcCo/aMWCNT的结构稳定性。电化学传感性能测试结果表明,TNPPcCo/aMWCNT修饰的玻碳电极在检测扑热息痛时,检测限可达0.4μmol·L^(-1)(S/N=3)且选择性较好,这归因于TNPPcCo与aMWCNT间的协同作用。Tetra-β-(p-nitrophenoxy)phthalocyanine cobalt(Ⅱ)/acidified multi-walled carbon nanotube(TNPPcCo/aMWCNT)composites were prepared by ultrasonic-assisted recombination.TNPPcCo/aMWCNT was characterized by scanning electron microscopy(SEM),transmission electron microscopy(TEM),X-ray photoelectron spectroscopy(XPS)and other methods.The results show that the unique surrounding substituents of TNPPcCo enhance theπ-πinteraction between TNPPcCo and aMWCNT and promote the combination of them,thus improving the structural stability of TNPPcCo/aMWCNT.The results of electrochemical sensing performance show that the detection limit of TNPPcCo/aMWCNT modified glassy carbon electrode for paracetamol is 0.4μmol·L^(-1)(S/N=3)with the good selectivity,which can be attributed to the synergistic interaction between TNPPcCo and aMWCNT.
