Synthesis of monolayer graphene on polycrystalline Ni and Ni-Cu bimetallic catalyst and study toward reuse of catalyst

Abstract : Graphene is a layer of sp2 hybridized carbon atoms with a thickness of only one atom. It possesses various magnificent properties that are not shared by other materials. To date, Chemical Vapor Deposition (CVD) is a promising method to produce wafer-scale graphene. From our study, monolayer graphene was grown directly on polycrystalline Ni foil under simple atmospheric pressure CVD with the assist of fast cooling. On the other hand, another facile technique was successful to grow uniform monolayer graphene simultaneously on both polycrystalline Ni and Cu foils using a Ni-Cu bilayer catalyst. The application of post-CVD fast cooling encourages the formation of Ni3C within the Ni foil, which subsequently enables the Ni foil to be reused again up to 6 cycles without causing a huge deviation. This work has successfully demonstrated a simple, novel and cost effective route to synthesize monolayer graphene with high quality
