▎ 摘　　要

NOVELTY - Preparation of porous graphene involves dissolving oxidized graphene in water, ultrasonically-dispersing to form oxidized graphene dispersion, dripping hydrogen peroxide solution, stirring, adding an ionic liquid to mixed solution, stirring mixture, carrying out hydrothermal reaction and freeze-drying. USE - Preparation of porous graphene for supercapacitor, sewage treatment and oil absorption. ADVANTAGE - The method enables simple preparation of porous graphene with large specific surface area.
