▎ 摘　　要

NOVELTY - Preparing activated carbon/graphene composite material comprises (1) mixing the biomass carbonizing material, graphene oxide and the first solvent, adding fermentation type biomass chain agent to react, solid-liquid separating to obtain biomass carbonizing material/graphene oxide, and (2) performing activating reaction of the biomass carbonizing material/graphene oxide to obtain activated carbon/graphene composite material. USE - The method is useful for preparing activated carbon/graphene composite material, which is useful for treating the anionic pollutant waste water or organic waste water (claimed). ADVANTAGE - The method: has strong linking effect, and synthesizing the active carbon/graphene composite material by one-step method, which can realize the activation of biomass carbonizing material, and insitu reduction of graphene oxide; does not need to carry out secondary processing to the commercial active carbon; reduces the energy consumption cost. The composite material: has stronger thermal conductivity, and the graphene formed during the heating process can accelerate the water vapor in the activation reaction process, or the diffusion rate of carbon dioxide on the surface of the carbonized material to achieve faster activation of pores. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for activated carbon/graphene composite material.
