A permselective membrane for size-sieving based H2/CO2 separation

Continuous H 2 /CO 2 separation via permselective membranes is highly sought after as pure H 2 plays a key role in H 2 economy. Aqueous nematic suspensions obtained by 1D dissolution of affordable sodium fluorohectorite allow for simple membrane fabrication by spray coating. The monolayer nanosheets have a uniform thickness of 1 nm and appreciable aspect ratio, thus self-assemble into defect-free membranes when applied onto porous mixed cellulose ester substrates. The perfectly textured restacki
