Abstract: Provided is a method for forming graphene nanoholes to form nanoholes in a graphene sheet, the method comprising a process (a) of forming a functional group-bonded region in a graphene sheet, and a process (b) of heating the graphene sheet having the functional group-bonded region to remove the functional group-bonded region to form nanoholes.

Abstract: Provided is a method for forming graphene nanoholes to form nonoholes in a graphene sheet, the method comprising a process (a) of forming a functional group-bonded region in a graphene sheet, and a process (b) of heating the graphene sheet having the functional group-bonded region to remove the functional group-bonded region to form nanoholes.
