dc.description.abstractCarbon dioxide (CO2) has been recognized as a major greenhouse gas causing global warming. Post-combustion CO2 capture is a crucial technology to directly capture CO2 in flue gases emitted from industries like coal- and gas-fired power plants. The principal goal of this thesis project is developing novel and efficient amino acid (AA)-based solid sorbents for post-combustion CO2 capture. Amino acid anion-functionalized ionic liquids (AAILs) have been synthesized and mainly employed as promising AA-based materials for CO2 capture study, due to their good reactivity with CO2. Three major research topics have been arranged, associated with the primary goal; namely 1) fundamental comparative CO2 capture study, 2) comprehensive CO2 capture study of supported AAIL sorbents and 3) development of promising supports for AAILs. Among the supported AAIL sorbents studied so far, 60 wt% 1-ethyl-3-methylimidazolium lysine ([EMIM][Lys])-loaded PE-SBA-15 and SBA-15-SA sorbents exhibited the highest CO2 adsorption capacities of 1.5 mmol/g-sorbent at 30 ˚C under a dry gas inlet (15% CO2). It is expected that the capacities can be still elevated to an optimum capacity range of 2-4 mmol/g-sorbent by any modifications of AAILs and/or supports. Some recommendations to improve the CO2 capture performances are described at the end of this thesis.en_US
