A simple approach towards nitrogen-doped graphene and metal/graphene by solid-state pyrolysis of metal phthalocyanine

Abstract

Here we reported a simple and efficient method for the in situ synthesis of nitrogen-graphene and metal/nitrogen-graphene in bulk by pyrolysis of copper phthalocyanine in an Ar atmosphere at 800 °C. By introducing copper foil as the substrate for pyrolysis of organometallic precursors, the rolling up process of graphene sheets into micro/nanoscroll was observed. We believe that a solid-pyrolysis approach opens opportunities for the mass production of graphene based materials at low cost and is useful in applications that need graphene as bulk materials.
