Deep eutectic solvents formed by solid azolide ionic liquids and ethylene glycol (EG) can efficiently capture CO2. Surprisingly, NMR and FTIR results indicated that CO2 reacted with the –OH group of EG to form a carbonate species rather than reacting with azolide anions to form a carbamate species during the absorption process.
