▎ 摘　　要

NOVELTY - Production of graphene and hydrogen involves heat-treating the shell of the organism, preparing graphene and hydrogen gas using the heat-treated biological shell and alcohol, collecting the generated hydrogen gas, and separating graphene by acid-treating the heat-treated shell. USE - Production of graphene and hydrogen used for hydrogen vehicle, and fuel cell. ADVANTAGE - The method is simple, economical and environmentally-friendly, and enables production of graphene and hydrogen with high purity, using alcohol as raw material even at low-temperature, capable of reducing the energy consumption because the reaction is made at low temperature, and has excellent electrochemical kinetic characteristics due to the smooth surface, and crystallinity.
