MOF Amine-functionalized MOF-based CO2 adsorbents

摘要

The present invention provides a method for manufacturing a carbon dioxide adsorbent in which amine is introduced at a high density into a metal-organic frame. The carbon dioxide adsorbent manufactured according to the manufacturing method of the present invention is excellent in adsorptivity and stability since high-density amine groups are introduced into the porous metal-organic frame. Moreover, the carbon dioxide adsorbent manufactured according to the manufacturing method of the present invention is suitable for capturing low concentration of CO_2 contained in actual exhaust gas, and is easy to be reused even in an environment where high concentration of CO_2 exists. The method of the present invention comprises: a step for activating the metal-organic frame; a step for forming a suspension; a step for sonicating the suspension; and a step for treating the sonicated suspension with microwaves.
