摘　　要：用固体微粒伏安法在电极表面直接获得了铜卟啉、铁卟啉及钴卟啉 ,在氯化钾支持电解质溶液中用循环伏安法对meso 四苯基卟啉 (H2 TPP)及现场合成的金属卟啉的固体电化学行为进行了表征 .作为电荷补偿 ,实验证明在固体金属卟啉还原及氧化过程中同时伴随有钾离子在晶胞中的迁移 ,文中对金属卟啉的形成机理及其电极反应机理进行了详细探讨 .Upon cyclic electrochemical polarization, traces of 5,10,15,20 tetraphenyl 21H,23H porphyrin(H 2TPP), which have been mechanically transferred to the surface of a paraffin impregnated graphite electrode, can incorporate copper, iron or cobalt ions from aqueous solution into the porphyrin ring to form CuTPP, FeTPPCl and CoTPPCl. The binding of metal ions by H 2TPP can be studied by voltammetry of immobilized microparticles. The mechanism of formation and reaction of the metalloporphyrins and their electrocatalytic properties were elucidated. [WT5HZ]
