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.
Key Highlight: ZIF-8 features a unique sodalite topology (11.6 Å β-cages connected by 3.4 Å 6-membered ring windows) optimizing selective gas separation and molecular sieving.
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.
ZIF-8 (Zeolitic Imidazolate Framework-8) is a representative metal-organic framework (MOF) fabricated from zinc and 2-methylimidazole (mIm). It features a sodalite structure consisting of four- and six-membered ring ZnN4 clusters, providing high thermal and chemical stability.
ZIF-8 typically exhibits a particle size of approximately 600 nm, a high specific surface area of ≥1500 ㎡/g, and a narrow pore size distribution ranging between 0.8 to 1.8 nm.
Due to its large surface area, adjustable porosity, and abundant active sites, ZIF-8 is widely used in adsorption, gas separation, drug delivery systems, catalysis, and biosensors.
ZIF-8 and its membranes provide superior molecular sieving properties compared to ultramicroporous zeolites. This is due to its narrow six-membered ring windows (~3.4 Å) and hydrophobic properties, which allow efficient separation of gas mixtures.
ZIF-8 features a cubic sodalite topology containing large β-cages of approximately 11.6 Å, which are interconnected by narrow 6-membered ring windows of about 3.4 Å.
ZIFs hold notable advantages over conventional zeolites as their hybrid framework structures offer greater flexibility in surface functionalization and modification, catering to diverse chemical applications.
