▎ 摘　　要

NOVELTY - The method involves growing the graphenes on a nickel foam. The three-dimensional graphene network is made by removing the nickel foam and growing zinc oxide nano/microparticles on the graphene surface. The hydrothermal method is used to finally obtain a hybrid composite material of zinc oxide, and three-dimensional graphene network as a macroporous monolith. USE - Method for preparing hybrid composite material of zinc oxide and three-dimensional graphene network used for manufacturing electrodes for energy storage and conversion device.
