摘要：

Deep eutectic solvents (DESs) were applied to the electrochemical CO2 reduction reaction (CO2RR). Choline-based DESs represent a non-toxic and inexpensive alternative to room-temperature ionic liquids (RTILs) as additives to the system or as electrolyte. Following the study on choline-based DESs this approach was generalized and simple and organic-soluble systems were devised based on the combination of organic chloride salts with ethylene glycol (EG), allowing the chlorides to be readily used as cocatalysts in the CO2RR. This approach negates the need for anion exchange and, because the chloride salt is usually the least expensive one, substantially reduces the cost of the electrolyte and opens the way for high-throughput experimentation.
