MESOPOROUS CELLULAR FOAM IMPREGNATED WITH IRON-SUBSTITUTED HETEROPOLYACID, PREPARATION METHOD THEREFOR, AND CARBON DIOXIDE SEPARATION METHOD USING SAME

摘要

The purpose of the present invention is to provide a novel adsorbent having excellent adsorption durability and high adsorption efficiency while having improved durability, thereby improving a carbon dioxide (CO2) separation process. The present invention relates to a mesoporous cellular foam impregnated with an iron (Fe)-substituted heteropolyacid including a mesoporous cellular foam support and an Fe-substituted heteropolyacid, and the mesoporous cellular foam impregnated with an Fe-substituted heteropolyacid has superior CO2 adsorption performance and exhibits excellent reproduction performance even after CO2 adsorption and desorption are performed several times through temperature changes, thereby enabling efficient and economical CO2 separation.
