    • A method for the production of graphene oxide and / or graphite oxide nanoplatelet structures having a thickness of less than 100 nm in an electrochemical cell, the cell comprising: (a) a positive electrode that is graphitic; (b) a negative electrode that may be graphitic or another material; (c) an electrolyte including: (i) organic anions in a solvent; (ii) non-oxidant polyatomic anions in a solution; and / or (ii) polyatomic anions in a solvent wherein the electrolyte has a hydrogen ion concentration of -1 mol dm -3 ; wherein the method comprises the step of passing a current through the cell to intercalate the anions into the graphitic positive electrode so as to exfoliate the graphitic positive electrode.
    • 一种用于在电化学电池中生产厚度小于100nm的氧化石墨烯和/或氧化石墨纳米片结构的方法,所述电池包括:(a)石墨的正极; (b)可以是石墨或其他材料的负极; (c)电解质,包括:(i)溶剂中的有机阴离子; (ii)溶液中的非氧化性多原子阴离子; 和/或(ii)溶剂中的多原子阴离子,其中所述电解质具有<1×10 -1 mol dm -3的氢离子浓度; 其中所述方法包括使电流通过所述电池以将所述阴离子插入到所述石墨正极中以剥离所述石墨正极的步骤。
