Research progress of CO₂ separation process with metal organic framework membrane material

Metal organic framework materials (MOFs) have the characteristics of high porosity, large specific surface area, adjustable pore channels and diverse structures. Adding MOFs to polymer membranes can significantly improve the permeability and selectivity of membrane materials to CO₂. The research progress of MOF membrane materials used in CO₂ separation process in recent years was reviewed, which includes (1) introducing CO₂ separation mechanism and synthesis process of MOF membrane materials; (2) summarizing the research and application progress of several main MOF membrane materials in CO₂ separation process; (3) proposing the development direction of MOF membrane materials in CO₂ separation field.
