High-Quality ZIF-8 MOFs from China Suppliers and Factory - Zeolitic Imidazolate Frameworks for Advanced Applications

acvbn

Zeolitic imidazolate frameworks (ZIFs) are innovative materials composed of transition metal ions, such as Zinc and Cobalt, paired with imidazolate (Im) linkers. These elements are arranged in tetrahedral coordination, surrounded by nitrogen atoms from the five-membered imidazole ring, which acts as a bridging linker to connect metal centers within a three-dimensional framework. The crystal structures of ZIFs resemble the topologies found in traditional aluminosilicate zeolites. As a leading factory in China, we are proud to offer high-quality ZIFs to suppliers and industries worldwide looking for advanced materials for various applications.

    Product Name ZIF-8
    Particle size ≈600 nm
    Specific surface area ≥1500 ㎡/g
    Pore size 0.8~1.8 nm

    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 Structural Advantages

    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.

    As we all know, ZIF-8 has shown up distinguished advantages and advances in adsorption, gas separation, drug delivery, catalysis and biosensor.
