▎ 摘　　要

NOVELTY - Preparation of graphene comprises taking platinum as counter electrode, copper foil as working electrode, and graphene oxide solution as electrolyte, performing electrodeposition, taking out deposited partially reduced graphene oxide, drying for 1 day at room temperature, adding dilute sulfuric acid as electrolyte, depositing, and performing electrochemical reduction. USE - Method for preparing graphene (claimed). ADVANTAGE - The method does not need corrosion resistance and toxicity reducing agent, is environment-friendly, simple and easy, greatly reduces test cost, has short experiment period, does not need protective atmosphere, and uses simple experiment device.
