Abstract
Zeolitic imidazole framework-8 is a kind of ZIF (a subclass of MOF) that comprises Zn2+ and 2-methylimidazole as center metal and organic linker, respectively. The structure of ZIF-8 resembles inorganic aluminosilicates. This material has gained a lot of attention from researchers due to its spectacular properties, including simple synthetic strategy, exceptional thermal and chemical stabilities, hydrothermal stability, high crystallinity and porosity, and tunable pores. ZIF-8 is one of the very few MOFs that can be synthesized at room temperature using an aqueous solution. ZIF-8 is considered a partially water-stable MOF and various strategies have been developed to improve its hydrothermal stability, such as the incorporation of hydrophobic groups in the ligand, carbonization, and shell-ligand exchange reaction. ZIF-8 is known for its exceptional thermal and chemical stabilities because of the strong interaction between Zn2+ and 2-methylimidazole, while many MOFs suffer from stability issues. ZIF-8 also shows great chemical stability on exposure to various electrolytes and organic solvents. Due to its remarkable properties, ZIF-8 finds use in a wide number of applications as an adsorbent, photocatalyst, sensor, gas separator, etc.
