Abstract

The growth mechanism of coal derived graphene films synthesized via chemical vapor deposition on copper substrates was investigated utilizing Raman spectroscopy, X-ray photoelectron spectroscopy, selected area electron diffraction, optical microscopy, and gas chromatography. The synthesis of coal derived graphene films is a two-step process, wherein the copper in annealed followed by flash pyrolysis of coal under hydrogen environment. The growth mechanism involves a copper catalyzed reaction to produce a carbon film within the first few minutes of synthesis, followed by a hydrogen catalyzed graphitization of the underlying carbon film to form graphene domains which merge together to form graphene films.
