Best China ZIF-8 Powder Metal Organic Frameworks (MOFs) - Top Suppliers and Factory Quality Service, Exporters

Zeolitic imidazolate frameworks (ZIFs) are advanced materials comprising transition metal ions, such as Zinc or Cobalt, along with imidazolate (Im) linkers arranged in tetrahedral coordination. The imidazole ring, featuring nitrogen atoms, acts as a bridging linker that connects the metal centers within a three-dimensional framework. These unique crystal structures of ZIFs exhibit topologies similar to those of aluminosilicate zeolites, making them highly sought after in various applications. As a leading factory in China, we specialize in the production of superior ZIFs, supplying high-quality materials to customers worldwide.

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

Q: What is ZIF-8 and who discovered it?

ZIF-8 is the most representative Zeolitic Imidazolate Framework (ZIF). It was first synthesized by Chen’s group and systematically named by Yaghi’s group. It is fabricated from zinc and 2-methylimidazole (mIm) to form a highly stable sodalite structure.

Q: What are the physical and structural specifications of this ZIF-8?

Our ZIF-8 features a particle size of approximately 600 nm, a high specific surface area of ≥1500 ㎡/g, and a pore size distribution of 0.8 to 1.8 nm. It possesses a typical cubic sodalite topology with 11.6 Å large β-cages.

Q: What are the primary application fields for ZIF-8?

ZIF-8 is widely utilized in key applications such as gas adsorption and separation, targeted drug delivery, heterogeneous catalysis, and advanced biosensors due to its flexible surface modification and high chemical stability.

Q: How does ZIF-8 perform in gas separation compared to zeolites?

ZIF-8 membranes offer outstanding molecular sieving advantages over ultramicroporous zeolites. Its narrow six-membered ring pores (~3.4 Å) and hydrophobic behavior allow for highly selective and efficient separation of gas mixtures.

Q: Why does ZIF-8 have high thermal and chemical stability?

Its stability is attributed to its robust sodalite framework structure, which consists of four- and six-membered ring ZnN4 clusters. This framework provides excellent resistance to thermal and chemical degradation while maintaining a high surface area and active sites.
