碘化四-(4-三甲胺苯基)卟啉合钴(简写Co(Ⅱ)TMAPPI)是较好的CO_2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CO_2电催化还原反应机理及有机碱(如咪唑)的助催化作用。
Cobalt tetrakis (4-trimethylaminophenyl) porphyrin (abbreviated as Co (Ⅱ) TMAPPI) is a good catalyst for the electrochemical reduction of CO 2. In the presence of imidazole, the current efficiency and CO production of this reaction were significantly increased, while pyridine was not. In this paper, the axial coordination of Co (Ⅱ) TMAPPI with different types of nitrogen-containing organic bases was reported to further elucidate the mechanism of CO 2 electrocatalytic reduction and the catalysis of organic bases such as imidazole.
