Abstract

The electrochemical behavior of a complex of cobalt with dimethylglyoxime Co(DMG)2(H2O)2 is studied by cyclic voltametry. Peaks corresponding to redox transitions Co(III)/Co(II) and Co(II)/Co(I) are observed in the potential region 0.4 to −1.8 V (Ag/AgCl). The product of reduction of the initial complex interacts with carbon dioxide to form a stable compound, probably an intermediate product of electrocatalytic reduction of CO2 to CO in the presence of N4-macrocyclic complexes of cobalt.
