NOVELTY - A graphene oxide/copper-2,3,6,7,10,11-hexahydroxytriphenylene composite material preparing method involves dissolving a graphene oxide nanosheet in a mixed solution of dimethylformamide and water, and mixing uniformly, adding copper nitrate trihydrate and 2,3,6,7,10,11-hexahydroxytriphenylene, reacting at 70-90 degrees C for 12 hours to obtain a product. The product is cooled to room temperature, the obtained product is centrifuged three times with ethanol at 12,000 rpm for 10 minutes obtain the finished product. USE - Method for preparing a graphene oxide/copper-2,3,6,7,10,11-hexahydroxytriphenylene composite material for electrochemical energy storage (claimed). ADVANTAGE - The method enables preparing a graphene oxide/copper-2,3,6,7,10,11-hexahydroxytriphenylene composite material with high specific surface area, more active sites and high conductivity and its energy storage performance is superior to that of a single copper-2,3,6,7,10,11-hexahydroxytriphenylene and graphene oxide material.
