“…Membrane-based technology has played a signicant role in gas purication, water desalination, fuel cells, catalysis, hemoltration, bioprocessing, pervaporation and other industrial separation processes. [1][2][3][4][5][6][7][8][9][10][11] Among them, organic solvent nano-ltration (OSN) is the most promising technology used for separation and purication in organic solvents and is commonly utilized for chiral separation, catalyst recovery, ionic liquid separation, solvent recycling, etc. 12 So far, several OSN membrane based on inorganic and organic (polymeric) materials have been developed and tested.…”
