Aqueous electrochemical reduction of CO2 has been of growing interest as a solution for GHG mitigation and due to the high diversity of products that can be selectively obtained depending on the electrocatalyst used (e.g. alcohols, hydrocarbons, CO etc.) . However, three main technical problems have been identified for the process feasibility: 1) low solubility of CO2 in aqueous media hinders mass transport, 2) high reaction overpotentials, and 3) obtaining a quality concentrated CO2 feedstock [3,4]
In this work, switchable polarity solvents (SPS) are used to capture and increase the CO2 concentration in aqueous media. SPS are emerging as an extremely versatile class of materials which shift polarity and solubility upon being exposed to a chemical agent, namely CO2 with water . Insoluble tertiary amines react with CO2 to form soluble ions [HNR3+] and bicarbonate . Hence, an ion exchange membrane assembly can be used to generate a localized acidic environment on the surface of the cathode electro-catalyst releasing CO2 for reduction.
Results of electrochemical analysis performed on metal supported catalysts will be presented
