CO 2 capture by a highly-efficient aqueous blend of monoethanolamine and a hydrophilic amino acid ionic liquid [C 2 OHmim][Gly]

•A hydrophilic ionic liquid [C2OHmim][Gly] was utilized to enhance MEA process for CO2 capture.•The optimum proportion of the blend was chosen as 0.7molL−1 MEA and 0.3molL−1 [C2OHmim][Gly].•The new absorbent had a reduced degradation and evaporation rate, an enhanced absorption capacity.•The antioxidation and thermal stability was greatly improved in MEA/[C2OHmim][Gly] solution.
