Abstract. The present work shows a new method in order to cost-effectively achieve the synthesis of graphene by Chemical Vapor Deposition (CVD). Unlike most usual processes, where precursors such as argon, H 2, CH 4, and high purity copper foil are used, the proposed method has replaced the previous ones by N 2, N 2 (90%) : H 2 (10%), C 2 H 2, and electrolytic copper (technical grade) since
