▎ 摘　　要

NOVELTY - The method involves preparing a solution in which a graphene oxide is dispersed. A source material for a metal oxide is added into the solution in which the graphene oxide is dispersed. A nanocomposite is formed by forming the metal oxide on a surface of graphene that is reduced using oxidation-reduction between the graphene oxide and the source material for the metal oxide, where reduction voltage of the source material for the metal oxide is 1.0 voltage or less, and the metal oxide is selected from a group consisting of metal phosphorus oxide, iron oxide and tin oxide. USE - Method for fabricating a graphene-based nanocomposite utilized in an academic and industrial fields. ADVANTAGE - The method enables uniformly synthesizing the graphene-based nanocomposites having superior characteristics in an environmental friendly process at a low cost. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene-based nanocomposite. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating process steps of fabricating a graphene-based nanocomposite.
