Synthesis of amine-functionalized ZIF-8 with 3-amino-1,2,4-triazole by postsynthetic modification for efficient CO2-selective adsorbents and beyond

The facile tuning of the gate size and the chemical functionalization of zeolitic imidazolate framework-8 (ZIF-8) were achieved by the postsynthetic modification with 3-amino-1,2,4-triazole. The resulting amine functionalized ZIF-8 particles enabled CO₂ selective adsorption and further chemical modifications.
