▎ 摘　　要

NOVELTY - Metal-doped graphene nanofiltration membrane comprises graphene nanoparticle layer deposited with a metal, a porous support layer embedded with the metal-doped graphene nanoparticle, and a membrane support layer. A transverse layer connecting the metal-doped graphene layer to the membrane support layer. The porous support layer embedded with the metal-doped graphene nanoparticle consists of a pore to allow the passing of liquid through the membrane. The metal is copper, silver, gold, and platinum. USE - Metal-doped graphene nanofiltration membrane used in various applications such as water purification, wastewater treatment, and desalination. ADVANTAGE - The metal-doped graphene nanofiltration membrane has highly efficient and selective filtration membrane for liquid filtration applications, and is mechanically stable, chemically robust, and has a high permeability and selectivity.
