In the present work a comparative survey has been done using highly oriented pyrolytic graphite (HOPG) and from graphite waste powder as starting material. Graphite waste is used for the purpose of reusing an industrial waste product and for a cheaper production cost of graphene. FT-IR spectra showed that the chemical oxidation was performed. XRD spectra proved graphene oxide nano-platelets and reduced graphene oxide formation. Raman spectra confirmed graphene oxide nano-platelets formation. And, AFM measurements show a layer thickness around 1 nm, and an average layer surface area of less than 500nm x 500nm.
