China Suppliers ZIF-8 Powder Metal Organic Frameworks (MOFs) - Mechanochemical Synthesis from Factory

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.
