CO2 Electroreduction in Organic Aprotic Solvents: A Mini Review

An annual increase of CO2 concentrations in the atmosphere causes global environmental problems, addressed by systematic research to develop effective technologies for capturing and utilizing carbon dioxide. Electrochemical catalytic reduction is one directions conversion into valuable chemicals fuels. The electrochemical at catalytically active electrodes aqueous solutions most studied. However, problems low selectivity target products hydrogen evolution are unresolved. Literature sources on cathodes nonaqueous mediums, particularly organic aprotic solvents, analyzed this article. Two cathodic considered—nonaqueous solvents containing water. current interpretation mechanism (IV) oxide CO main factors influencing rate reduction, Faradaic efficiency products, ratio direct given. influence nature solvent analyzed, including topography cathode, values cathode potential, temperature. Emphasis placed role water impurities reducing electroreduction overpotentials formation new formate H2.
