▎ 摘  要

NOVELTY - Catalytic metal film comprises a first catalytic metal layer (110) comprising a first metal, and a second catalyst metal layer (130) containing a second metal different from the first metal on the first catalyst metal layer. USE - The catalytic metal film is useful for producing graphene structure (claimed). ADVANTAGE - The catalytic metal film produces graphene structure having large grain size, and improved quality. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) graphene structure comprising the catalytic metal film (10) and a graphene layer (140) provided on the second catalytic metal layer; and (2) producing graphene structure, comprising (a) preparing a catalytic metal film having a second catalytic metal layer comprising a second metal different from the first metal on the first catalytic metal layer including the first metal, and (b) providing the catalytic metal film with a gaseous carbon source, heating and reacting at reaction temperature to synthesize graphene composite on the catalytic metal film, where the graphene is formed on the second catalytic metal layer. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the graphene structure.
