▎ 摘　　要

NOVELTY - Preparation of porous graphene oxide comprises taking natural crystalline flake graphite as raw material, utilizing Hummers method, obtaining graphite oxide at 10-50 degrees C by magnetic force stirrer for 10-30 minutes, uniformly mixing to obtain suspension, adding 0.1-1 mg/ml prepared graphite oxide suspension into cuboid electrolytic bath, cleaning the graphite electrode set in two inner sides of electrolytic cell, applying alternating electric field and peeling graphite oxide into single layer graphene oxide at 10-30 V under frequency of 50-5000 Hz for 30-120 minutes. USE - Method of preparation of porous graphene oxide (claimed). ADVANTAGE - The method is simple, has low cost, is safe and has no pollution. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the preparation of porous graphene oxide.
