▎ 摘　　要

NOVELTY - Preparing graphene-based porous carbon network involves drying monolayer oxide graphene dispersion liquid by atomization drying to obtain graphene microspheres. The graphene microspheres are mixed with biomass carbon source and activator in mass ratio of 100:10-200:100-300, crushed over 300-400 meshes, and transferred into mold at filling rate of 90-100%. The mold is sealed, and the mixture is carbonized, activated, and washed to obtain final product. USE - Method for preparing graphene-based porous carbon network (claimed) used for air purification, water treatment, microwave absorbing material, and chemical material. ADVANTAGE - The method enables to prepare graphene-based porous carbon network which has large specific surface area and pore volume, and has low density.
