▎ 摘  要

NOVELTY - Preparation of porous carbon-coated graphene composite, involves mixing carbohydrate, catalyst and active material with graphene, carrying out hydrothermal reaction to obtain hydrogel, soaking hydrogel with solvent, drying under atmospheric pressure, mixing dried product with pore-forming agent and reducing at high temperature. The active material is ethanolamine salt, polyethylene ammonium salt, cetyl ammonium bromide and/or poly(vinyl alcohol). USE - Preparation of porous carbon-coated graphene composite (claimed). ADVANTAGE - The method enables preparation of porous carbon-coated graphene composite with excellent synergistic effect.
