▎ 摘  要

NOVELTY - Ultra-high specific surface area carbon material comprises graphene structure having a two-dimensional or three-dimensional long periodic rule structure at a predetermined interval of 0.5-100 nm, reflecting the shape of a pore of a zeolite and the regularity of the super cage of the zeolite which is the connection pattern of the pore, where the carbon material comprises a metal atom to be bonded to the graphene edge of the graphene structure through an oxygen atom, and the metal atoms are chosen from titanium, zirconium, silicon, magnesium, barium, strontium, zinc, iron, aluminum, lanthanum, nickel, cobalt, chromium, and lead. USE - The ultra-high specific surface area carbon material is used for gas storage materials such as hydrogen, methane, and carbon dioxide, electrode material for electrochemical device, composite matrix, electrically conductive material and carbon membrane. ADVANTAGE - The method improves chemical or thermal stability of the ultra-high specific surface area carbon material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for producing the ultra-high specific surface area carbon material, which involves forming a zeolite-graphene composite by introducing an organic substance to the pores of the zeolite, and carbonizing the organic substance, forming a graphene structure by removing the zeolite, mixing an alkoxide of a metal atom chosen from titanium, zirconium, silicon, magnesium, barium, strontium, zinc, iron, aluminum, lanthanum, nickel, cobalt, chromium, and lead with the graphene structure in a solvent, and performing mixing and stirring step of forming the ultra-high specific surface area carbon material in which the metal atoms are bonded to the graphene edges of the graphene structure via oxygen atoms.
