▎ 摘  要

NOVELTY - Preparation of asphalt-based activated carbon composite loaded with graphene oxide, involves cutting or grinding asphalt particles, adding an emulsifier, dispersing in water to obtain an emulsified asphalt, dissolving potassium hydroxide in distilled water, adding graphene oxide and a dispersant to obtain a graphene oxide stable dispersion containing activator, mixing the emulsified asphalt and graphene oxide dispersion, adding a coupling agent, heating, evaporating to obtain a potassium hydroxide/graphene oxide/emulsified asphalt mixture, carbonizing the mixture, washing, and drying. USE - Preparation of asphalt-based activated carbon composite loaded with graphene oxide. ADVANTAGE - The method enables aperture control and adjustment of heat conductivity, reduces energy consumption, and provides efficiency composite with excellent desorption regeneration ability and prolonged service life.
