The composition of functional groups, morphology, defect structure, and surface fractal dimension D_S 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 D_S = 2.5-2.7 on a scale of 0.4 nm-120 μm.
