Synthesis of graphene-like materials by graphite oxide reduction

Graphene-like materials were produced by the reduction of graphite oxide with a series of chemical reagents and high-temperature treatment. Hydrazine hydrate, hydroxylamine hydro-chloride, sodium borohydride, and sodium sulfite were used as reducing agents. The obtained materials were studied by elemental and thermal gravimetric analyses, scanning electron microscopy, X-ray diffraction, and IR and Raman spectroscopy. Depending on the used reducing agents, the graphene-like materials contained different amounts of residual oxygen.
