▎ 摘 要
NOVELTY - The method for preparing graphene using biomass raw material, involves (1) removing impurity from biomass raw materials, crushing, (2) mixing treated biomass raw material with chemical solvent, adding catalyst, and (3) heating the biomass raw material at high temperature and carrying out ultra-high pressure treatment to obtain graphene. USE - Method for preparing graphene using biomass raw material. ADVANTAGE - The environmentally-friendly method enables economical preparation of graphene using biomass raw material.
