FAU -type zeolite membrane has a great potential in gas/liquid separation,catalysis and membrane reactors.In this paper,some methods of FAU- type zeolite membrane synthesis are introduced firstly.Subsequentlg, secondary growth method and seed types,seeding method,supports for FAU - type membrane synthesis are described and reviewed in detail.Furthermore,applications of FAU - type zeolite membrane in gas/liquid separation are also discussed briefly.
