▎ 摘　　要

NOVELTY - The present invention discloses a graphene formation device, which comprises a reaction tank, a reaction unit, a first electrode, a second electrode and a power supply unit. The reaction tank contains an electrolyte. The reaction unit is disposed in the reaction tank and includes a first member, a second member, and a porous holder. The second member is disposed around the periphery of the first member. The porous holder is disposed between the first member and the second member. Wherein, a graphite material is accommodated in the reaction unit, and the first member, the porous holder and the second member have a plurality of corresponding holes. The first electrode passes through the graphite material and is connected to the bottom of the reaction unit. The second electrode is disposed in the reaction tank, and the second electrode is disposed around the periphery of the reaction unit. The power supply unit is electrically connected to the first electrode and the second electrode.
