Abstract
With the aim of finding a suitable electrocatalyst for the efficient reduct ion of carbon dioxide, the electrochemistry of nickel (II) complex of 1,3,6 ,9,11,14-hexaazatricyclo [12.2.1.1] octadecane was studied using cyclic vol tammetry (CV) and controlled-potential electrolysis (CPE) techniques in the presence and absence Of CO2 in 100% H2O, CH3CN-H2O mixtures (20-100%) and DMF-H2O (70-100%) mixtures. The efficiency of this process is determined us ing the coulometry technique. CO is the major product in the gaseous phase and HCOOH the sole product formed in the solution phase.
