Abstract:

With the extensive application of monovalent cations in the transformation and upgrading of traditional industries such as energy conversion and storage,industry,the efficient separation of monovalent cation mixtures has become a significant demand.The monovalent cation sieving technology based on new separation membrane materials was reviewed,especially the design and application of nanoscale and sub-nanoscale ion channel membranes.The innovative applications of materials such as graphene,graphene oxide(GO),metal-organic framework(MOF),crown ether,MXene,and covalent organic framework(COF) in ion-sieving and their potential to improve selectivity and transport efficiency were analyzed in detail.The regular principle of ion transport,such as size screening,chemical selectivity and surface charge etc.,was further discussed,and the intrinsic relationship between material structure and ion separation performance was revealed.At the same time,the current challenges,such as membrane stability,scale production and cost-effectiveness,were pointed out,and the future research direction was prospected.

Key words: ion sieving, monovalent cation, sub-nanometer ionic channel, selective separation, ion membrane
