NOVELTY - Preparing reduced graphene oxide from kish graphite involves subjecting provision of kish graphite, pre-treating kish graphite. The intercalation of kish graphite is carried out with a persulfate salt and an acid at room temperature to obtain intercalated kish graphite. The expansion of the intercalated kish graphite at room temperature to obtain expanded kish graphite, oxidized expanded kish graphite to obtain graphene oxide and reduced graphene oxide into reduced graphene oxide. USE - Method for preparing reduced graphene oxide from kish graphite.
