▎ 摘　　要

NOVELTY - Preparing graphene-based material composite biomass activated carbon involves adding graphene-based materials to fungal culture medium at 5-1000 mg/L; connecting fungus, standing still at room temperature or shaking culture at 28 degrees C for 150 rotation/minute, until cluster of flocculent hypha complex grows, and medium is clear and bright; taking out mycelium complex and rinse with deionized water; placing washed mycelium complex in calciner for carbonization at 600 degrees C for 1 hour, during which time is continuously protected by argon to obtain graphene-based composite biomass activated carbon. USE - Method for preparing graphene-based material composite biomass activated carbon. ADVANTAGE - The method is simple in process, strong in controllability, and low in cost; provides new ideas and production methods for development of high-performance, low-cost, and high-efficiency biomass activated carbon and composite biomass activated carbon materials; and have potential of chemical industry production.
