▎ 摘　　要

NOVELTY - Method for producing nanoporous graphene membrane involves depositing a hexaiodo-substituted macrocycle onto a substrate comprising a Ag(111) surface, coupling the macrocycle to form a nanoporous graphene sheet, layering the nanoporous graphene sheet and substrate onto a nanoporous membrane with the nanoporous graphene sheet in contact with the nanoporous membrane, and etching away the substrate. USE - The method is used for producing a nanoporous graphene membrane which is used in water purification, chemical warfare agents (CWA) decontamination, radionuclide separation from ground water, gas separation, and in desalination treatment. ADVANTAGE - The method is cost-effective, has high performance filtration, and greatly enhances the performance of both sensors and wearable protection.
