ELECTROCATALYTIC CONVERSION OF CARBON DIOXIDE IN LIQUIDS EXPANDED BY CARBON DIOXIDE

摘要

Processes for the electrochemical reduction of CO2 are provided. In an embodiment, such a process comprises passing a current through a CO2 expanded liquid medium under a pressure greater than 0.2 MPa and less than 7.4 MPa in the presence of a catalyst to reduce and convert CO₂ to one or more products, wherein the CO₂ expanded liquid medium comprises dissolved CO₂, a liquid solvent, and a dissolved electrolyte, and wherein the liquid solvent and the dissolved electrolyte are selected to provide a concentration of the dissolved CO₂ of at least 2 M at the pressure.
