This Instructable (loosely) follows the method of graphene production described by C&EN, who cite a paper published by Parvez, Wu, et. al. In the paper (Exfoliation of Graphite into Graphene in Aqueous Solutions of Inorganic Salts), it is explained that putting a graphite electrode and a platinum electrode into a solution of inorganic salts (ammonium sulfate works best, they say) with a 10V supply (graphite = anode, platinum = cathode) causes the graphite to be torn apart by electrochemical activity to become graphene! Graphene has attracted much hype and study recently. One of its near-term applications may be in high density supercapacitors.
