▎ 摘　　要

NOVELTY - Preparing graphene involves mixing biomass material, anionic surface active agent and water and then subjecting the mixed material to carrying out hydro-thermal reaction at 150-250 degrees C for 1-24 hours to obtain precursor. The obtained precursor is mixed with metal catalyst to obtain a metal-containing catalyst precursor and then the metal-containing catalyst precursor is heated to obtain the desired product. USE - Method for preparing graphene (claimed). ADVANTAGE - The method enables to prepare graphene with high surface activity and high degree of graphitization.
