Ion-retention properties of graphene oxide/zinc oxide nanocomposite membranes at various pH and temperature conditions

open access: yesScientific Reports
Laminar graphene oxide (GO) is a promising candidate material for next-generation highly water-permeable membranes. Despite extensive research, there is little information known concerning GO's ion-sieving properties at high acidic/basic pH and ...
