摘    要:用循环伏安法和旋转环盘电极技术研究中位-四-磺基苯基卟啉的铁、锰配合物(FeTPPS和MnTPPS)的氧化还原性能.比较均相溶液中它们对氧电还原的催化作用,发现FeTPPS的电催化活性优于MnTPPS,但尚依赖于溶液介质的性质.用电聚合方法将FeTPPS和MnTPPS分别嵌入聚吡咯中制成聚合物修饰电极,可改善电催化性能,不仅使氧还原电位正移,而且增大还原电流.讨论了聚合物修饰电极对氧还原的可能影响.

关 键 词:金属卟啉,聚合物修饰电极,氧还原,电催化

Abstract:The redox properties of metal complexes of meso tetrakis(p sulfonatophenyl) porphyrin, FeTPPS and MnTPPS, were investigated by using cyclic voltammetry and RRDE technique. By comeprating the catalytic reduction of dioxygen in the presence of MTPPS in solution,it was found that the electrocatalytic activity of FeTPPS is superrior to MnTPPS, but depends on the nature of soluion media. MTPPS was incorporated into polypyrrole by electropolymerization of pyrrole, the as forming membrane electrodes facilitate the electroreduction of dioxygen. The role of polymer electrodes in oxygen reduction was discussed.
Keywords:Metalloporphyrins   Polymer membrane modified electrodes   Oxygen reduction   Electrocatalysis
