Effect of coordinating N−H groups and light irradiation in the electrocatalytic CO2 reduction to CO with two new Co complexes, CoH and CoMe, is reported. CoH displays catalytic CO2 reduction at the CoII/I redox potential (−1.9 V vs. Fc, ca. 40 % FYCO), which improves upon light irradiation (−1.9 V, 81 % FYCO). FTIR-SEC and DFT calculations identify [CoI−CO]+ as one of the key intermediates in the reaction pathway.

吡啶氨基钴配合物在电化学二氧化碳还原中配位-NH基团和光的双重效应

报道了在电催化 CO 2还原为 CO 与两种新的 Co 配合物Co HCo Me中配位 NH 基团和光照射的影响。Co H在 Co II/I氧化还原电位(-1.9 V 与 Fc,约 40 % FY CO)下显示出催化 CO 2还原,这在光照射(-1.9 V,81 % FY CO)下有所改善。FTIR-SEC 和 DFT 计算确定 [Co I -CO] +是反应途径中的关键中间体之一。
