摘      要:Developing highly efficient electrocatalysts for the CO_(2) reduction reaction(CO_(2)RR)has attracted increasing interest in the past ***,we report on the design and synthesis of Fe porphyrin 1 with an appended N,N-di(2-picolyl)ethylenediamine(DPEN)unit that boosts electrocatalytic activity for CO_(2)-to-CO conversion in acetonitrile with water as the proton *** mimicking carbon monoxide dehydrogenase(CODH),1 has poly-pyridine/amine units located at the active site to form hydrogen-bonded water-containing networks that enable fast proton *** protonated and positively charged DPEN unit can also stabilize CO_(2) reduction intermediates through electrostatic and hydrogen-bonding *** factors make 1 a highly active electrocatalyst for the CO_(2)RR by achieving a TOFmax of 5.0​×​10^(4)​s^(−1) with water providing the *** critical roles of the DPEN unit in the CO_(2)RR are further supported by theoretical *** work is significant to highlight the benefits of using molecular catalysts to elucidate structural effects.
