The homogeneous-dispersed graphene oxide was prepared by the improved Hummers method, which would be reduced to graphene with the reducing agent called hydrazine hydrate. The X-ray diffraction, Infrared spectroscopy, Raman spectra and Transmission electron microscopy were used to analysis the phase, morphology and structure of the graphene and graphene oxide. The results show that the graphene oxide and reduced graphene oxide prepared via this method, whose degree of oxidation and reduction are high; Also obtained a higher well-disperses and less structural imperfection of the graphene that was manufactured in the reducing system that added ammonia reduction
