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.
