研究室紹介
Professor Ki Bong Lee's research lab specializes in the development of advanced sorbent materials for high-temperature carbon dioxide (CO₂) capture, with a focus on metal oxides, hydrotalcites, and nitrogen-doped carbon materials. The lab investigates the fundamental surface chemistry and adsorption mechanisms of these materials to enhance CO₂ uptake capacity and selectivity under industrially relevant conditions, particularly in the context of post-combustion and pre-combustion CO₂ capture. Key research directions include the design of chemically modified sorbents through doping and impregnation (e.g., K₂CO₃ promotion) and the use of computational methods to understand the role of specific functional groups in CO₂ binding.

15Physisorbents like zeolites, activated carbons, silica, and alumina gels have been traditionally used for separation of bulk or trace carbon dioxide from a gas mixture using a pressure or a thermal swing adsorption process. These processes are generally operated at near ambient or at moderate temperatures (say <100 °C) because the equilibrium sorption capacity and selectivity of sorption of CO 2 on the physi-sorbents rapidly decrease at higher temperatures. Recently, a variety of reversible CO 2
The amount of anthropogenic CO 2 emission keeps increasing worldwide, and it urges the development of efficient CO 2 capture technologies. Among various CO 2 capture methods, adsorption is receiving more interest, and carbonaceous materials are considered good CO 2 adsorbents. There have been many studies of N-containing carbon materials that have enhanced surface interaction with CO 2; however, various N-containing functional groups existing in the carbon surface have not been investigated in d
