▎ 摘　　要

NOVELTY - Manufacture of graphene involves chemically reacting a carbon-containing material, water steam and a carbonate aqueous solution as a raw materials in a reactor at temperature of less than 200 degrees C and predetermined pressure and removing generated hydrogen and water. USE - Manufacture of graphene. ADVANTAGE - The method is environmentally-friendly and enables simple and economical manufacture of graphene at mild temperature. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of the manufacture of graphene. (Drawing includes non-English language text) Heater (5) Reactor (6) Cooler (7) Solid-liquid-separation device (8) Mixing tank (9)
