▎ 摘  要

NOVELTY - Preparing three-dimensional foam graphene comprises (i) pre treating foamed metal; (ii) placing the pretreated foamed metal in a reaction kettle, adding carbon source, heating and carrying out hydrothermal carbon coating reaction, cooling to room temperature, to obtain carbon-coated foamed metal; (iii) washing the carbon-coated foamed metal and drying; (iv) heat treating the step (iii) product in inert atmosphere, to obtain three-dimensional foam graphene precursor; and (v) removing, washing and drying the step (iv) product, to obtain final product. USE - The three-dimensional foam graphene is useful for energy storage, catalysis and adsorption. ADVANTAGE - The method is simple, easy, environmentally friendly, and economical; and has mild preparation condition. The product has porous structure, high specific surface area and good flexibility.
