▎ 摘　　要

NOVELTY - An oxidized graphite is heat-treated at 250-350 degrees C, to obtain expanded graphene. USE - Preparation of expanded graphene (claimed) used for hydrogen storage material, separator for fuel cell and capacitor. ADVANTAGE - The method provides expanded graphene at low temperature, in short period of time.
