    Research output: Patent


    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 x 10-1 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.
