Methods for the production in an electrochemical cell of metal oxide deposited graphene and/or graphite nanoplatelet structures having a thickness of less than 100 nm, in a cell having a positive electrode which is graphitic and an electrolyte comprising an intercalating anion and a metal cation, wherein the metal is selected from ruthenium, manganese, iridium, tin, and silver. The methods comprising the step of passing a current through the cell to intercalate anions into the graphitic positive electrode so as to exfoliate the graphitic positive electrode and such that the metal ion undergoes electrodeposition in the form of the corresponding metal oxide to produce the metal oxide deposited graphene and/or graphite nanoplatelet structures. |
