Abstract

The present invention concerns a method for producing a nanoporous 2D film, for example a graphene membrane. The method comprises exposing the non-porous 2D film to a reactive plasma and etching the 2D film so as to provide said nanoporous 2D film. In an embodiment, the method is a two-step method, comprising the initial deposition, by sputtering, of a protective layer comprising an inorganic oxide or nitride, before etching the 2D film. The nanoporous 2D films are useful for gas-separation.
