Abstract: Disclosed herein are porous graphene filters, each consisting of a carbon monoatomic layer having small holes formed therein during the graphene formation, a plurality of the porous graphene filters being used to selectively filter a specific material from a mixture of at least two different materials, a method for manufacturing the same, and a filtering apparatus using the same. The method comprises: separately forming a first graphene filter having a first hole of a first size and a second graphene filter having a second hole of a second size, during deposition of carbon atoms generated from a carbon source for formation of graphene, by substituting the carbon atoms, in part, with a substitution atom generated from a substitution source, the second size being larger than the first size; and arranging the first graphene filter and the second graphene filter in a filter body equipped with an inlet and an outlet.

Abstract: Disclosed are a porous graphene member having through-holes formed therein, a method for manufacturing the porous graphene member, and an apparatus for manufacturing the porous graphene member using the method. The method comprises: introducing a carbon source and a substitution reaction source into a deposition furnace; thermally decomposing the carbon source and the substitution reaction source simultaneously to generate carbon atoms and substitution atoms, respectively, wherein the carbon atoms are deposited on a substrate present within the deposition furnace to form a graphene film consisting of a monoatomic layer structure, and during the deposition of carbon atoms, the substitution atoms not only interfere with covalent bonds between the carbon atoms to cause crystal defects, but also substitute for parts of the carbon atoms to in situ form through-holes in the graphene, thereby creating the porous graphene member; and releasing the porous graphene member from the substrate.
