Abstract
Official abstract text for this publication.
A method of preparing graphene includes supplying a gas on a metal catalyst, the gas including CO 2 , CH 4 , and H 2 O, and reacting and cooling the resultant.
First claim
Opening claim text (preview).
What is claimed is: 1. A graphene-encapsulated metal nanoparticle prepared by a method including supplying a gas on a metal catalyst, the gas including CO 2 , CH 4 , and H 2 O; and reacting and cooling the resultant, wherein the supplying supplies the gas in a mole ratio of the CH 4 , CO 2 , and H 2 O gases at about 1:0.20-0.50:0.01-1.45. 2. The graphene-encapsulated metal nanoparticle of claim 1 , wherein the metal nanoparticle includes at least one metal selected from Ni, Co, Cu, Fe, Rh, Ru, Pt, Au, Al, Cr, Mg, Mn, Mo, Si, Sn, Ta, Ti, W, U, V, Zr, brass, bronze, stainless steel, and Ge, or an alloy including two or more of the aforementioned metals. 3. The graphene-encapsulated metal nanoparticle of claim 1 , wherein the metal nanoparticle has a diameter of about 1 to about 50 nm. 4. The graphene-encapsulated metal nanoparticle of claim 1 , wherein the graphene-encapsulated metal nanoparticle is used in one of a light emitting material for a display, an electrode material of a battery or a solar cell, and an in vivo drug delivery material. 5. A hollow graphene nanoparticle prepared by removing the metal nanoparticle from the graphene-encapsulated metal nanoparticle according to claim 1 .
