▎ 摘  要

NOVELTY - Producing porous graphene involves dispersing graphene in N-methyl-2-pyrrolidone solution ultrasonically to obtain uniform graphene dispersion liquid and then loading the graphene dispersion liquid on filter membrane by vacuum pump at negative pressure to obtain graphene thin film. The obtained graphene thin film is kept in electrolyte solution as electrode to obtain the desired product. USE - Method for producing porous graphene used as supporting material (claimed). ADVANTAGE - The method enables to produce porous graphene in quick and cost-effective manner, with controllable size of pores, and without high temperature condition.
