▎ 摘 要
NOVELTY - The preparation method of porous graphene involves dispersing graphene and graphene oxide in phosphate buffer solution to obtain mixture of graphene and graphene oxide, and carrying out circulation volt-ampere scanning with electrode (I) as working electrode and three-electrode system. USE - The method is useful for preparing porous graphene (claimed). ADVANTAGE - The method enables simple, economical and quick preparation of porous graphene.
