What is Holey Graphene?
Holey Graphene is a modified form of graphene, a single layer of carbon atoms arranged in a hexagonal lattice. Unlike regular graphene, holey graphene contains nanoscale holes or pores strategically introduced into its structure. These perforations enhance its properties, making it suitable for a wide range of advanced applications.
