▎ 摘　　要

NOVELTY - Preparation of mesoporous graphene with high adsorption capacity comprises dispersing metal salt and inorganic nanoparticle sol in deionized water, sonicating to obtain uniform dispersion, adding straw to dispersion, heating, mixing, evaporating deionized water, drying in oven, placing in tube furnace, calcining under inert gas protection, washing to remove template and drying. USE - Method of preparing mesoporous graphene with high adsorption capacity used for antibiotics (claimed). ADVANTAGE - The method has wide sources, low cost and is simple. The graphene has high specific surface area and high degree of graphitization.
