▎ 摘  要

NOVELTY - Preparing porous graphene material comprises mixing graphene-based deposit with an acid solution to obtain porous graphene material, where the acid in the acid solution is sulfuric acid and/or phosphoric acid, and the content of the acid is 75-100 wt.% of the total mass of the acid solution. USE - The porous graphene material is useful for adsorption carrier of metal ions, organic solvent, gas, and loading of metal nanoparticles. ADVANTAGE - The porous graphene material has wide pore size distribution, large pore diameter, high porosity and large specific surface area. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for porous graphene material prepared by the as specified above.
