▎ 摘　　要

NOVELTY - The manufacturing method of iron oxide-graphene nanocomposite involves mixing iron oxide precursor, graphene oxide, and ferric chloride with a solvent to obtain a mixed colloidal solution, spraying the aerosol droplets on the mixed colloidal solution, transferring into a heating furnace, and spray pyrolyzing at 300-600 degrees C. USE - Manufacturing of iron oxide-graphene nanocomposite of supercapacitor (claimed). ADVANTAGE - The method manufacturing of iron oxide-graphene nanocomposite with wide specific surface area and excellent electric capacity by simple process.
