Abstract
A transformational energy efficient technology using ionic liquid (IL) to couple with monoethanolamine (MEA) for catalytic CO2 capture is disclosed. [EMmim+][NTF2−] based catalysts are rationally synthesized and used for CO2 capture with MEA. A catalytic CO2 capture mechanism is disclosed according to experimental and computational studies on the [EMmim+][NTF2−] for the reversible CO2 sorption and desorption.
