Reduction Method And Electrolysis System For Electrochemical Carbon Dioxide Utilization

Abstract

The present disclosure relates to electrochemical utilization of carbon dioxide. The teachings may be embodied in methods and electrolysis systems in which carbon dioxide is introduced into an electrolysis cell and reduced at a cathode. For example, a reduction method for carbon dioxide utilization by means of an electrolysis system may include: delivering carbon dioxide into a chamber containing a cathode; introducing a first material in the cathode chamber, enabling catalysis of a reduction reaction of carbon dioxide to a hydrocarbon compound or to carbon monoxide; and introducing a second material together with the electrolyte or a reactant/electrolyte mixture into the cathode chamber or metered separately into the cathode chamber. The second material enables cocatalysis of the reduction reaction by promoting charge transfer from the cathode to the first material. The first and second materials react with one another in situ as precursor and form hydrido-metal complexes or metal-carbonyl hydrides within the cathode chamber.
