▎ 摘　　要

NOVELTY - A graphene oxide loaded nano manganese dioxide is prepared by centrifuging in high speed the graphite oxide to dehydrate; mixing manganese chloride tetrahydrate, the dehydrated graphite oxide and isopropyl alcohol; subjecting to ultrasonic treatment; heating the mixed solution while stirring; adding potassium permanganate and water; stirring; centrifuging; washing; drying; and grinding obtained residue. USE - Method of preparing graphene oxide loaded nano manganese dioxide. ADVANTAGE - The method is quick and simple, has mild reaction conditions, and prepares product having excellent electrochemical property under mild condition. DESCRIPTION OF DRAWING(S) - The drawing is a flow chart of a method of preparing graphene oxide loaded nano manganese dioxide. Drawing includes non-English language text.
