▎ 摘　　要

NOVELTY - Preparing three dimensional graphene material comprises (i) preparing graphite oxide using pressure graphite oxide; (ii) dispersing graphene oxide in an organic solvent by ultrasound to obtain a graphene oxide solution; and (iii) mixing the alkali solution and the organic solvent to obtain a mixed solution, and contacting the graphene oxide solution of step (ii) with the mixed solution for 20-60 minutes. USE - The three dimensional graphene material is useful in the fields of charge storage, pollutant adsorption and microwave absorption. ADVANTAGE - The method: does not require the use of expensive, precise equipment and long and cumbersome processes; produces product instantly at room temperature without additional energy consumption; is rapid; and produces three-dimensional graphene with orderly arrangement of graphene sheets.
