ZIF-67 (CAS number: 46201-07-4) is a cobalt-based zeolitic imidazolate framework, composed of Co(II) metal centers tetrahedrally coordinated by 2-methylimidazolate (mIm) linkers. This coordination enables ZIF-67 to crystallize in a sodalite (SOD) topology, resulting in a robust network. Owing to its zeolite-like structure, ZIF-67 exhibits excellent porosity (surface area ca. 1600 m²/g) and thermal stability (ca. 500 °C under inert environment).

With the high surface area and abundant active sites, a ZIF-67/PVDF membrane can capture pharmaceutical pollutants, such as ciprofloxacin, from wastewater. The membrane exhibits adsorption capacity of 4087.5 μg/cm² across a wide pH range.

ZIF-67 is also widely applied as a template for battery electrode materials, such as Co_xS_y composite encapsulated in a carbon shell. The resulting Co_xS_y electrode delivers an excellent capacity of 875.6 mAh/g at a current density of 100 mA/g.
