▎ 摘　　要

NOVELTY - Preparing graphene material involves adding the graphene oxide to obtain a suspension of graphene oxide to disperse medium; spray drying the suspension to obtain graphene oxide particles; and reducing the graphene oxide particle by atmosphere. USE - For preparing graphene material; and as the electrode material of the super capacitor, catalyst carrier or optical material (claimed). ADVANTAGE - The method obtains macro-porous graphene micro-particles; and is used as super capacitor electrode material, catalyst carrier or optical material, where the capacity reaches 120 F/g.
