Oily wastewater has adverse effects on ecosystems,human health and Marine life.The traditional oil-water separation method has high energy consumption and low separation efficiency,which limits its application in emulsion separation.In recent years,oil-water separation membranes based on metal-organic framework(MOFs)have been widely applied in oil-water separation due to their flexible structure,large surface area,high porosity,easy fabrication and adjustable functionality.The separation mechanism and advantages of MOFs-based oil-water separation membrane are systematically discussed in this paper.On this basis,the classification of MOFs-based oil-water separation membrane and its performance in practical application are discussed.In addition,the synthesis methods and characteristics of different kinds of MOFs-based oil-water separation membranes are introduced in detail,and the research prospect of MOFs-based oil-water separation membranes is prospected,which provides theoretical basis and technical guidance for realizing its large-scale application.
