Abstract: A method of preparing a metal-carbon composite of a core-shell structure through simultaneous vaporization, in which a metal particle constitutes a core and carbon constitutes a shell, with the metal-carbon composite prepared in the form of powder and supported on a supporter, and a metal-carbon composite of a core-shell structure prepared by the same. In these methods, the metal-carbon composite of the core-shell structure is prepared through simultaneous vaporization of metal and carbon precursors and does not require separate post-processing. Further, in the metal-carbon composite of the core-shell structure prepared by these methods, a carbon shell covers a portion or the entirety of a surface of a metal core, whereby the metal particles can be prevented from suffering agglomeration, separation or corrosion when subjected to harsh process conditions at high temperatures for long durations under strong acid and alkali conditions, thereby providing high performance and high durability.

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.
