The composition of functional groups, morphology, defect structure, and surface fractal dimension DS of reduced graphene oxide (RGO) synthesized by reduction of graphene oxide by hydrazine hydrate and heat treatment under hydrogen atmosphere at 400°C are considered. The obtained materials were studied by scanning electron microscopy, infrared and Raman spectroscopy, nitrogen adsorption-desorption, and elemental analysis. It was found that the synthesis method does not affect the fractal dimension of the RGO surface, which is DS = 2.5-2.7 on a scale of 0.4 nm-120 μm.
