摘要： A method for the manufacture of reduced graphene oxide from Kish graphite including: the provision of Kish graphite, the intercalation of Kish graphite 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, the mixture of the expanded Kish graphite with at least an acid and an oxidizing agent while the gases generated during the expansion step are still at least partially present so that the expanded Kish graphite is simultaneously oxidized, exfoliated and reduced into reduced graphene oxide.
