The application of existing ternary betaine (Be)-based deep eutectic solvents (DESs) faces inevitable limitations due to the low regenerability and water absorption capability DESs. In this study, three Be-based DESs with different molar ratios were prepared by adding promoter diethanolamine (DEA) binary system Be ethylene glycol (EG). effects DEA, temperature, flow rate on CO2 then investigated. At a ratio 1:5:8 (Be:EG:DEA), capacity reached 0.207 g CO2/g DES at an temperature 30 °C gas 50 mL/min. addition contents triggered dissolution, forming + system. added inhibited Evaluation showed that their capacities remained above 0.176 after five cycles absorption–desorption.
