▎ 摘　　要

NOVELTY - Preparing a graphene-metal oxide three-dimensional porous composite material involves producing a graphene nanosheet into a three-dimensional porous graphene macrostructure and using the same as an electrode. The metal oxide is deposited on the surface of the electrode by an electrochemical method to prepare a graphene-metal oxide three-dimensional porous composite material. USE - Method for preparing a graphene-metal oxide three-dimensional porous composite material (claimed). ADVANTAGE - The method enables to prepare a graphene-metal oxide three-dimensional porous composite material in simple, cost-effective and eco-friendly manner with mild reaction.
