英文摘要: The electrochemical behaviors of two copper Schiff base complexes, [N,N′-bis(2-R-phenyl-salicylidenaminato)Cu(II)] complex, (CuL2-Me for R = Me, and CuL2-Cl for R = Cl), and [N,N′-bis(salicylaldimine)propylenediimino Cu(II)] (CuL′), as well as the stability of their reduced forms in a N,N-dimethylformamide (DMF) solution were studied using cyclic voltammetry. We also investigated the homogeneous activity of the CuL′ complex as a bifunctional electrocatalyst for direct electrocatalytic reduction of CO2 to CO2 - and indirect CO2 activation by the product of O2 electrocatalytic reduction to yield peroxydicarbonate anions, C2O6 2-. In each case, the complex exhibited an excellent electrocatalytic behavior for the activation of carbon dioxide. Both electrocatalytic reduction of CO2 and that of O2 are ligand-based. However, the complex promotes the electrocatalytic reduction of CO2 better as compared to the free ligand. Crown Copyright © 2015 Published by Elsevier Ltd. Citation statistics:
