Exploring the recent developments in membrane electrode assembly electrolyzer for the conversion of CO2 to CO

초록

Electrochemical CO2 reduction (eCO2R) is a promising strat-egy for reducing atmospheric CO2. Recent developments in membrane electrode assembly (MEA) have enabled expo-nential performance improvements by facilitating CO2 supply and reducing energy losses with unique configurations. As CO is a platform chemical for high-energy-density fuels, its pro-duction by eCO2R MEA has been intensively studied. This review provides an overview of the recent studies on the development of MEA for CO production. Various catalysts and their modification strategies for achieving high CO production and selectivity in MEA have been introduced. Furthermore, the cell operating and extrinsic conditions of the electrodes, which can significantly affect CO production, are reviewed. Finally, the remaining challenges for advanced CO production MEA are presented.
