Abstract
Summary
The study shows that a dinuclear molecular copper complex immobilized on graphitized mesoporous carbon catalyzes the electrochemical conversion of CO₂ to hydrocarbons (methane and ethylene) with total Faradaic efficiencies of up to 60%. In 0.1 M KCl, a high selectivity toward C₂ products is achieved, with a Faradaic efficiency of 40%. The influence of local pH, pore structure, and the carbon support on mass transport and the formation of highly reduced products is demonstrated. Although spectroscopy after 2 h of bulk electrolysis indicates that the molecular complex is still present, morphological analysis reveals that newly formed copper clusters act as the actual active sites during catalysis.
