Structure & Performance Profile
ZIFs have advantages over zeolites such that the hybrid framework structures are expected to have more flexibility in surface modification. Among a large variety of ZIFs, ZIF-8 is the most representative one first synthesized by Chen’s group, and then systematically named by the Yaghi’s group. It can be fabricated by zinc and mIm with a sodalite structure consisting of a four- and a six-membered ring ZnN4 cluster, which has good thermal and chemical stability, especially large specific surface area, adjustable porosity and abundant active sites.
As we all know, ZIF-8 has shown up distinguished advantages and advances in adsorption, gas separation, drug delivery, catalysis and biosensor. ZIF-8 possesses the typical cubic sodalite topology with 11.6 Å large β-cages, which are connected by 6-membered ring windows (~3.4 Å). ZIF-8 and its membranes perform significant sieving advantages over ultramicroporous zeolites in selective separation of gas mixture contributing to the narrow six-membered ring pores (~3.4 Å) and hydrophobic behavior.
Frequently Asked Questions
ZIF-8 features a particle size ranging between 50~200 nm, a pore size of 0.8~1.8 nm, and a high specific surface area of ≥1500 m²/g, providing abundant active sites for functional interactions.
ZIF-8 possesses a sodalite structure fabricated by zinc and 2-methylimidazole (mIm) consisting of four- and six-membered ring ZnN4 clusters. It contains typical cubic sodalite topology with 11.6 Å large β-cages interconnected by 6-membered ring apertures (~3.4 Å).
Compared to traditional zeolites, the hybrid framework structure of ZIFs provides greater flexibility for surface modification, adjustable porosity, and hydrophobic properties that prevent common moisture-degradation issues.
ZIF-8 membranes achieve high selectivity in gas mixture separation due to their narrow six-membered ring windows (~3.4 Å) and distinct hydrophobic behavior, surpassing ultramicroporous zeolites in molecular sieving performance.
ZIF-8 is widely utilized in adsorption, gas separation, targeted drug delivery, heterogeneous catalysis, and biosensing, owing to its high thermal/chemical stability and tunable pore networks.
ZIF-8 was first synthesized by Chen’s group and subsequently systematically classified and named by Professor Omar Yaghi’s research team.
