제목 Synthesis of amine-functionalized ZIF-8 with 3-amino-1,2,4-triazole by postsynthetic modification for efficient CO2-selective adsorbents and beyond
초록 The facile tuning of the gate size and the chemical functionalization of zeolitic imidazolate frameworks (ZIFs) have been considered efficient strategies for various potential applications including gas membranes and catalysts. Herein, we demonstrate the synthesis of amine-functionalized ZIF-8 (ZIF8-A) with 3-amino-1,2,4-triazole (Atz) by postsynthetic modification. The acquired ZIF8-A substantially enhanced CO2/N2 and CO2/CH4 selectivity at 35 oC compared to ZIF-8 since the Atz conversion enhanced chemical interactions with CO2 due to the introduction of amine moieties. The gate size control of ZIF-8 by the replacement of Atz was thoroughly investigated by extensive transport experiments and density functional theory computational simulations. We believe that our current work can provide promising platforms for designing ZIF-based materials with versatile properties including precise control of the gate size and the incorporation of various functional groups.
