Metal-doped graphene nanofiltration membrane used in various applications such as water purification, wastewater treatment, comprises graphene nanoparticle layer deposited with metal, porous support layer embedded with metal-doped graphene nanoparticle, membrane support layer, and transverse layer.

PUNETHA V D, KALPETIYA S

Covalently cross-linked graphene oxide nanofiltration membrane useful in nanofiltration, reverse osmosis and oil-water separation, has e.g. single graphene oxide material without any exogenous crosslinking agent participating in crosslinking, and interception objects are small neutral molecules.
