▎ 摘　　要

NOVELTY - Preparing graphene nano sheet by electrochemical cathode stripping comprises using solution containing hydroxide as an electrolyte, a raw material containing graphite as an electrochemical cathode, and a conductive material as an electrochemical anode, the electrolyte, the electrochemical anode and the electrochemical cathode constitute an electrochemical circuit, applying voltage between electrochemical cathode and the electrochemical anode, and the electrochemical cathode peels off graphite to prepare graphene nano sheet. USE - The method is useful for preparing graphene nano sheet by electrochemical cathode stripping. ADVANTAGE - The nano sheet: is environmentally friendly.
