• The invention allows for graphene production from readily available solid hydrocarbons such as coal, biocoal, and biochar. The invention does not require hydrogen injection or vacuum conditions, thereby reducing complexity and cost over other methods of graphene production.
• The invention allows graphene to be produced globally at lower temperatures and costs and is amenable to standard engineering reactor scaleup. Popular applications of graphene include solar panels, foldable touchscreens, and bionic devices.
• The lifetime of reactors, vessels, and transportation vessels made of Fe or Fe alloys can be increased by depositing graphene directly on the surface which will prevent the metal from oxidizing….
