Abstract
Provided are a graphene preparation apparatus, including: a chamber having a space for preparation of graphene; a first electrode and a second electrode disposed in the chamber to be separated a predetermined distance from each other, the first electrode and the second electrode supporting a catalytic metal and receiving electric current for preparation of the graphene to heat the catalytic metal using Joule heating; additional heaters disposed at opposite sides of the catalytic metal, respectively, and heating the catalytic metal to compensate for a temperature difference between both end regions and a central region of the catalytic metal heated using Joule heating induced by the first electrode and the second electrode; and a current supply unit supplying electric current to the first electrode and the second electrode.
