A method for producing graphene. The method includes loading an open-cell porous backbone material with particulate graphite, submersing at least part of the graphite-loaded porous backbone material in a solution, and applying a cathodic potential to the graphite-loaded porous backbone material, wherein the cathodic potential suffices to exfoliate graphene.
A method for the continuous production of graphene. The method includes flowing a suspension of graphite particles into a conductive, open-cell porous material that is disposed within a reaction vessel, applying a cathodic potential to the conductive, open-cell porous material, wherein the cathodic potential suffices to exfoliate graphene, and flowing a suspension of the exfoliated graphene out from the conductive, open-cell porous material.
