▎ 摘　　要

NOVELTY - A carbon-based functional material comprises activated carbon, graphene composite as carrier, and functional nanoparticles as filler supported on carbon-based material surface or pores. The formation of carbon-based material is loaded with functional filler composite structure. USE - The carbon-based functional material is useful for toxic gas purification, waste gas treatment, sterilization and bacterial inhibition, and industrial and domestic water purification process. ADVANTAGE - The carbon-based functional material has excellent adsorption performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of carbon-based functional material, which involves (1) mixing zinc powder, silver nitrate solution, titanium dioxide solution, aqueous graphene oxide, activated carbon and surfactant according to solid content mass ratio under vacuum, stirring for more than 30 minutes at speed of greater than 100 rpm until the mixture is uniformly mixed, (2) placing mixed solution obtained in step (1) in sealed reactor and carrying out hydrothermal reaction at 130-200 degrees C for 1-6 hours, (3) cooling mixed solution after completion of the hydrothermal reaction in step (2), filtering, centrifuging, carrying out solid-liquid separation process, and drying separated solid to obtain carbon-based functional material precursor, and (4) calcining carbon-based functional material precursor obtained in step (3).
