▎ 摘　　要

NOVELTY - Manufacture of graphene involves mixing graphite and sulfuric acid, producing graphite slurry, adding permanganate to the graphite slurry, preparing permanganate sulfuric acid solution, adding water, providing the reaction mixture into aqueous hydrogen peroxide solution, filtering, dispersing the filtrate in hydrochloric acid, drying, oxidizing the graphite, sonicating the oxidized graphite, peeling the graphite oxide, and reducing the resultant product by reducing agent. USE - Manufacture of graphene (claimed). ADVANTAGE - The method enables safe and economical manufacture of graphene with high productivity.
