Add-Ons
ZIF-8 (Zeolitic Imidazolate Framework-8, Zn(MeIM)2, where MeIM = 2-methylimidazolate) is a sodalite-topology metal-organic framework built from tetrahedrally coordinated Zn2+ nodes linked by methylimidazolate rings. The Zn–N–C bond angle (~ 145°) mimics the Si–O–Si bridging angle in classical aluminosilicate zeolites, combining the high chemical/thermal stability of zeolites with the tunable porosity of MOFs.
The key structural features of theZIF-8 are: (1) Sodalite (SOD) Topology: Pore Cavity: Large spherical central cage with a diameter of ~ 11.6 Å. Pore Aperture: Narrow 6-membered ring windows with a nominal crystallographic diameter of ~ 3.4 Å. (2) "Gate-Opening" Framework Flexibility: The 2-methylimidazolate linkers undergo a coordinated rotational "swinging" motion (gate opening) under guest molecule pressure. This increases the effective accessible window diameter from its nominal ~3.4 Å up to ~ 4.0–4.2Å, enabling diffusion of molecules nominally larger than the static aperture. (3) Textural Properties: BET Surface Area: Typically 1300–1800 m2/g; Micropore Volume: 0.60–0.68 cm3/g. Framework Density: ~ 0.95 g/cm3. (4) Robust Chemical Stability: Hydrophobic surface chemistry gives ZIF-8 resistance to boiling water, high-humidity streams, and alkaline environments (pH 9–14), though it degrades in acidic media (pH < 5) due to protonation of the imidazolate linker.
Mechanochemical (solvent-free) synthesis of ZIF-8 via planetary or vibratory ball milling replaces conventional solvothermal routes that use bulk organic solvents (such as DMF or excess methanol). By reacting solid zinc oxide (ZnO) or basic zinc carbonate with 2-methylimidazole (Hmim) under mechanical shear and impact forces, high-crystallinity ZIF-8 powder is produced with near-zero liquid waste and high space-time yields.
