METHOD FOR SYNTHESIZING GRAPHENE-BASED NANO COMPOSITE MATERIAL, AND GRAPHENE-BASED NANO COMPOSITE MATERIAL SYNTHESIZED USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a method capable of easily forming a nano composite material from a metal oxide and a graphene material in a short time.SOLUTION: The method comprises: a step in which a solution into which graphene oxide is dispersed is provided; a step in which a raw material substance for forming a metal oxide is added to the solution; and a step in which a nano composite material in which the metal oxide is formed on at least one side of the graphene surface reduced using an oxidation-reduction reaction between the graphene oxide and the raw material substance for forming a metal oxide is formed, and the reduction potential of the metal oxide is 1.0 V or lower, where the metal oxide includes one selected from the group consisting of FePO, FeOand SnO.
