▎ 摘　　要

Aided by Oxone, water-dispersible graphene of 2-5 atomic layers was electrochemically fabricated from graphite in one step without any extra stabilizers or additives. Oxone as a novel electrolyte and the electrochemically enhanced oxidation were responsible for the excellent aqueous dispersibility, effective exfoliation and the reasonably high yield (up to 60.1%).
