Title:
METAL-DOPED GRAPHENE PLATE
Document Type and Number:
WIPO Patent Application WO/2017/018855
Kind Code:
A1
Abstract:
The present invention relates to a metal-doped graphene plate and, specifically, relates to a graphene plate in which a post-transition metal or a metalloid is doped to the edge of graphene. The present invention discloses the graphene plate, wherein a post-transition metal or a metalloid, which cannot be produced by conventional graphene production processes, is doped to the edge of graphene, thereby exhibiting excellent electrochemical activity and durability. Due to the features, the graphene plate according to the present invention can be applied more quickly and easily in various fields, and can contribute to commercialization of graphene.
