摘要： 在研究了碘化四-(4-三甲胺苯基)卟啉合钴(Co(Ⅱ)[p-N(CH3)3]TPPl)对CO2还原的电催化活性的基础上[1],我们展开了对镍、铜、锌等金属卟啉对CO2电催化还原影响的研究。

Abstract: The catalytic activity of several water-soluble metallo-porphyrin complexes, M(Ⅱ)[p-N(CH3)3]TPPI (M = Co, Ni, Cu, Zn; [p-N(CH3)3]TPPI = tetrakis (4-trimethylammoniophenyl) porphyrin iodide), for the electroreduction of CO2 has been studied by means of controlled-potential electrolysis in aqueous solutions. It was found that Co( Ⅱ )[p-N(CH3)3]TPPIis active but other metalloporphyrins show no activity. In the presence of Co( Ⅱ )[p-N(CH3)3]TPPl the main product of CO2 reduction was CO, but small amounts of HCOOHwere obtained. The effects of electrolytes, catalyst concentrations, electrode materials and potentials on the reduction of CO2 were investigated.
