Engineering metal–organic frameworks (MOFs) based thin-film nanocomposite (TFN) membranes for molecular separation

Progressing thin-film membrane designs for post-combustion CO2capture: performance or practicality?

“…The IP TFC membranes have already been a commercialized technology for reverse osmosis (RO) water desalination for over two decades with high technological maturity. [193][194][195] Exploring the transferability of the IP technology for gas separation is nothing but a reasonable move. While studies showed that IP TFC membranes synthesized using conventional PA monomers were unable to obtain attractive CO 2 /N 2 separation performance, CO 2 -philic groups like PEO or CO 2 -reactive amine-containing motifs could be incorporated into the PA layer to achieve promising, multifaceted performance enhancements by substituting the aqueous monomer.…”

Highly Efficient Arginine Intercalated Graphene Oxide Composite Membranes for Water Desalination

“…However, their high cost and low desalination capacity hinder their future applications. Besides this, several membrane systems based on carbon nanotubes, − metal–organic frameworks, − metal carbides, − covalent organic frameworks, − transition-metal dichalcogenides, − zeolites, , etc. are widely investigated for salt and dye separation from water.…”

Carbon Nitride Quantum Dot-Based Thin-Film Nanocomposite Membranes for Efficient Dye Removal

“…These attributes can confer many advantageous properties to membranes, including high permeability, super hydrophilicity, fouling resistance, chlorine tolerance, and so on. To date, a variety of nanomaterials, such as carbon nanotubes, graphene oxide, silica, silver, metal–organic frameworks (MOFs), , zeolite nanoparticles, polyhedral oligosesquioxane (POSS), and clay nanosheets, have been explored to fabricate TFN membranes. However, one of the primary challenges associated with these membranes is the poor compatibility between incorporated nanomaterials and PA matrix, which often generate nonselective void during membrane preparation.…”
