NOVELTY - A nickel oxide/reduced graphene oxide nano composite material preparing method involves utilizing a multi-walled carbon nanotube as a raw material. A graphite oxide nanosheets with lamellar structure is obtained by using Hummer method. The ultrasonic dispersion is performed on the graphite oxide nanometer sheet, cooled at room temperature, filtered and washed with water and ethanol. The washed graphite oxide nanometer sheet is dried to obtain precursor composite material. The precursor composite material is heated to prepare a nickel oxide/reduction-oxidation graphene nano-composite material. USE - Method for preparing nickel oxide/reduced graphene oxide nano composite material. ADVANTAGE - The composite material has excellent electrochemical properties. DETAILED DESCRIPTION - A nickel oxide/reduced graphene oxide nano composite material preparing method involves utilizing a multi-walled carbon nanotube as a raw material. A graphite oxide nanosheets with lamellar structure is obtained by using a Hummer method. The ultrasonic dispersion is performed on the graphite oxide nanometer sheet using ethanol solvent at 140-180 degrees C for 10-12 hours. The graphite oxide nanometer sheet is cooled at room temperature, filtered and washed with water and ethanol. The washed graphite oxide nanometer sheet is dried in vacuum to obtain a precursor composite material. The precursor composite material is heated at 200-250 degrees C for 3-5 hours under air atmosphere to prepare a nickel oxide/reduction-oxidation graphene nano-composite material.
