Zusammenfassung:The present invention relates to a post-functionalized zeolite, a method for preparing the same, and a catalyst and an adsorbent comprising the same, wherein the zeolite is prepared by subjecting the zeolite having a negative charge as a nucleophile to a nucleophilic substitution reaction with a hydrophobic aliphatic or aromatic hydrocarbon having a leaving group or an electron withdrawing group as an electrophile. By functionalizing micropores of the zeolite, an effect of adsorbing carbon dioxide is excellent, thereby being usefully used as the adsorbent or catalyst. 본 발명은 후관능화된 제올라이트, 이의 제조방법, 이를 포함하는 촉매제 및 흡착제에 관한 것으로, 상기 제올라이트는, 친핵체로서 음전하를 갖는 제올라이트를 친전자체로서 이탈기 또는 전자흡인기를 갖는 소수성의 지방족 또는 방향족 탄화수소와 친핵성 치환반응을 시키어 제올라이트의 미세기공을 관능화함으로써 이산화탄소를 흡착하는 효과가 우수한바, 흡착제 또는 촉매제로서 유용하게 사용할 수 있다.
