【 摘 要 】

Recently, separation and purification identified as a huge and stringent challenge in industrial processes and environmental protection. Being high efficient and advanced technology, metal-organic framework (MOF) membranes and membrane processes have presented tremendous potentials in application of gas separation. Compared with conventional bulk MOF membranes, the dense and polycrystalline MOF ultrathin membranes with nanometre-thick layers have shown outstanding gas separation performances due to minimized mass-transfer barrier. In this paper, three typical synthetic strategies of MOF ultrathin molecule-sieving membranes are introduced, and their performances in gas separation are compared.
