نبذة مختصرة : International audience ; The combination of CO2 capture and electroreduction to different value-added molecules seems to be a solution for industrial decarbonization. Different electrodes materials were studied in the last years for the selective reduction of carbon dioxide to different value-added molecules such as methanol. So far, Cu-based catalysts appear to be a unique material that is able to reduce CO2 to high-value products. On the other hand, Pd-based catalysts are less known for this type of application. Thus, the focus in this work is on the synthesis and comparison of the performances of Cu and Pd-based catalysts for methanol production. The other challenge is the development of the electrolyte for selective CO2 capture and electroreduction. To this date, ionic liquids show promising results for high CO2 absorption. This type of organic solvents has also multiple advantages such as wide electrotrochemical windows and good ionic conductivity. However, the high price of ionic liquids leads to the research of more affordable alternatives such as deep eutectic solvents. Hence, the aim of this study is to develop a DES-based electrolyte for CO2 capture and electroreduction to different value-added molecules using Pd-based catalysts.
