▎ 摘　　要

NOVELTY - Reduction of graphene oxide involves reducing graphene oxide using metal carrier catalyst and hydrogen. The graphene oxide is dispersed in polar organic solvent before reduction. USE - Reduction of graphene oxide (claimed). ADVANTAGE - The reduction method does not use toxic components. Since toxic components do not remain on the reduced graphene, additional cleaning work is eliminated. The catalyst can be reused efficiently after the reduction process.
