摘要： 碘化四-(4-三甲胺苯基)卟啉合钴(简写Co(Ⅱ)TMAPPI)是较好的CO2电化学还原反应的催化剂。有咪唑存在时此反应的电流效率和CO产量明显提高,吡啶则否。本文报道Co(Ⅱ)TMAPPI与不同类型含氮有机碱的轴向配位反应研究,以进一步阐明CO2电催化还原反应机理及有机碱(如咪唑)的助催化作用。

Abstract: The equilibrium constants and coordination numbers for axial reaction of cobalt(Ⅱ)tetrakis(4-trimethylamino phenyl)-porphyrin iodide hydrate(abb. Co(Ⅱ)TMAPPI)withnitrogen containing organic bases were measured by spectral technique. The results showthat Co(Ⅱ)TMAPPI forms 1:2 adducts with imidazoline(Im)and benzimidazoline(PhIm),but 1:1 adducts with pyridine(Py)and n-propylaniline(P1NH2). The mechanism of the auxi-liary catalytic effect of nitrogen containing organic bases on the electrocatalytic reductionof CO2 with Co(Ⅱ)TMAPPI was discussed.
Key words: cobalt tetrakis(trimethylamino phenyl)-porphyriniodide, organic base, coordination reaction
