Progress in research on channel microenvironment regulation of graphene-based CO2 separation membrane

Graphene, as a two-dimensional nanosheet with the thickness of monoatomic layer, has become a unit of high-performance carbon capture membranes due to its unique physical property. The ultrathin thickness of graphene-based membranes is conducive to the preparation of ultrathin membranes in order to improve the flux of separation membranes. Upon that, the adjustable physicochemical property endows multiple microenvironment within the two-dimensional channel of graphene. In view of the multiple mass transfer mechaisms of CO₂ separation membranes, it highlights the strategies and progress of precision controllable of physiochemical microenviroment within the two-dimensional channel of graphene in recent years. Expecting to provide a clear thinking for the reasonable design and controllable equipment of graphene-based CO₂ separation membranes.
