Task specific ionic liquids(TSILs) have great potential for CO2 capture at room temperature but, at higher temperature, as a reason of thermal stability the adsorption capacity decreases. In this work, 1-ethyl-3-methylimidazolium amino acid {[EMIM][AA]} organic-inorganic hybrid material was synthesized via grafting method in order to enhance the applicability of ionic liquid with thermally robust inorganic substrate for the high temperature CO2 capture. The material analysis was carried out by using XRD, SEM, 13C-NMR, 29Si-NMR and CO2-TPD. The developed material is expected to exhibit fast adsorption-desorption kinetics as well as good capacity in high temperature CO2 capture.
