▎ 摘　　要

NOVELTY - The material has a base material provided with a nitrogen-doped graphene and a copper ferrite, where the mass ratio of the base material nitrogen-doped graphene and copper ferrite is 1: 5 to 1: 10. The base material is formed with a pneumatic doped graphite material. A ferric nitrate and a copper nitrate are mixed with a graphene oxide solvent. A urea is added with a mix solvent, which is provided with a hydro-thermal kettle, where the hydro-thermal reaction temperature is 20 to 200 degree Celsius. USE - Nitrogen-doped graphene/copper ferrite nano-composite material. ADVANTAGE - The material has better application prospect in an energy storage element, and achieves electro-catalysis aspect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nitrogen-doped graphene/copper ferrite nano-composite material preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical illustration of a nitrogen-doped graphene/copper ferrite nano-composite material preparation method.
