Abstract
A graphene-based membrane, along with its methods of formation and use, is provided. The graphene membrane includes at least two graphene-oxide layers. Each graphene-oxide layer has a plurality of graphene-oxide flakes, with each graphene-oxide flake having a planar graphene structure with oxygen moieties extending therefrom. The graphene-based membrane can have a thickness of about 2 nm to about 20 nm. Such a graphene-based membrane can be utilized to remove ions from water.
