Abstract

See full text

Provided is a graphene production method using Joule heating, including: a catalytic metal placement step in which a catalytic metal is disposed on a pair of electrodes disposed inside a chamber; a gas supply step in which a carbon-containing reaction gas and a carrier gas for transporting the reaction gas are supplied into the chamber; a heating step in which the catalytic metal is rapidly heated to a temperature required for synthesis of graphene; a temperature maintenance step in which the temperature of the catalytic metal is maintained to form the graphene on the catalytic metal; and a cooling step in which the catalytic metal is cooled to prevent local occurrence of hotspots on the graphene formed on the catalytic metal, wherein the heating step, the temperature maintenance step, and the cooling step constitute one cycle of temperature control and the cycle is repeated for a predetermined process time.
