Bifunctional Ionic Deep Eutectic Electrolytes for CO₂ Electroreduction.

ABSTRACT: CO₂ is a low-cost monomer capable of promoting industrially scalable carboxylation reactions. Sustainable activation of CO₂ through electroreduction process (ECO₂R) can be achieved in stable electrolyte media. This study synthesized and characterized novel diethyl ammonium chloride-diethanolamine bifunctional ionic deep eutectic electrolyte (DEACl-DEA), using diethanolamine (DEA) as hydrogen bond donors (HBD) and diethyl ammonium chloride (DEACl) as hydrogen bond acceptors (HBA). The DEACl-DEA has -69.78 °C deep eutectic point and cathodic electrochemical stability limit of -1.7 V versus Ag/AgCl. In the DEACl-DEA (1:3) electrolyte, electroreduction of CO₂ to CO₂ ^•- was achieved at -1.5 V versus Ag/AgCl, recordi
