Immobilization of amino acid ionic liquids into nanoporous microspheres as robust sorbents for CO2 capture

Supported nanoporous microspheres immobilized with amino acid ionic liquids (AAILs) as robust sorbents were developed for CO2 capture. AAILs could be facilely immobilized into porous support materials. The developed sorbents exhibited fast kinetics as well as good sorption capacity, and can be regenerated and reused. The presented strategy may pave the way for developing AAIL-functionalized sorbents with high capacity and fast CO2 transport kinetics.
