NOVELTY - Synthesis of an electrochemically exfoliated graphene involves (i) performing hydroxide intercalation of a graphite sample to provide a hydroxide intercalated graphite by applying an electrochemical intercalation current to an intercalation anode comprising the graphite sample in a basic aqueous intercalation electrolyte in electrical contact with an intercalation cathode, (ii) exchanging the basic aqueous intercalation electrolyte for an inorganic or organic salt exfoliation electrolyte, and (iii) exfoliating the hydroxide intercalated graphite to provide the electrochemically exfoliated graphene. The exfoliation of the hydroxide intercalated graphite involves applying an electrochemical exfoliation current to an exfoliation anode comprising the hydroxide intercalated graphite in the inorganic or organic salt exfoliation electrolyte in electrical contact with an exfoliation cathode. USE - Synthesis of electrochemically exfoliated graphene used as catalyst, catalyst support and adsorption media for fuel cell, sensor and battery.
