Abstract: Disclosed herein are a carbon dioxide adsorbent with an amino acid-based amine group grafted thereto, and a method for manufacturing the same by grafting an ionic liquid-loaded porous support, having large surface area, with an amine group through ion exchange and neutralization with an amino acid. Having excellent carbon dioxide adsorption performance, selectivity for carbon dioxide, thermal stability, and reusability, the carbon dioxide adsorbent of the present invention can be effectively applied to the prevention of environmental pollution produced by carbon dioxide release.

Abstract: Disclosed is an aerogel for capturing carbon dioxide (CO2 ) and, more particularly an aerogel for capturing CO2 and a preparation method for the same, where the aerogel for capturing CO2 is prepared using a magnesium precursor and an aluminum precursor by an epoxide-driven sol-gel method and a subsequent drying method using supercritical carbon dioxide to have a high CO2 adsorptive performance at elevated temperature. There is provided an aerogel for capturing CO2 to selectively adsorb CO2 at elevated temperature, thereby contributing to the reduction of the CO2 emission that is mainly responsible for atmospheric pollutions by using the high-efficiency aerogel for capturing CO2 with high CO2 selectivity, high CO2 adsorption performance, and good recyclability in the repetitive adsorption-desorption processes.
