▎ 摘　　要

NOVELTY - Graphene is prepared by pretreating biomass material, mixing with metal catalyst and solvent, loading to obtain catalyst-loaded biomass material, mixing with pore-forming agent, and heating at 700-1200 degrees C for 5-10 hours in which biomass material is agriculture and forestry waste, tea leaf, and/or seaweed plant. USE - Preparation of graphene. ADVANTAGE - Graphene has high specific surface area, conductivity, and electrochemical performance and reduced internal resistance, and preparation is environment-friendly and low-cost.
