Research Development on the Synthesis of Zeolitic Imidazolate Framework-8 and Membranes

As a typical zeolitic imidazolate frameworks(ZIFs),ZIF-8has many important applications in gas storage,absorptions/separations,catalysis and chemical sensors.The synthesis methods of ZIF-8crystal and nanocrystalline have been summed up and clarified,such as solvothermal synthesis,microwave-assisted synthesis,room temperature synthesis and microfluidic synthesis.The synthetic strategies of ZIF-8crystal are analyzed.Potential use of microfluidic technology in continuous,fast and controllable synthesis of ZIF-8crystalline with narrow particle size distribution are discussed and highlighted.And the fabrication of ZIF-8membranes are also summarized including direct synthesis,secondary growth,surface functionalization and special seeding,contra-diffusion(counter-diffusion)synthesis.
