▎ 摘　　要

NOVELTY - A preparation method of elemental nickel/graphene nanocomposite material comprises using pulse laser to immerse graphene oxide solution of nickel target material into liquid phase laser ablation, preparing hydroxyl nickel oxide/graphene oxide compound solution, under the normal temperature normal pressure adding reducing agent to obtain hydroxyl nickel oxide/graphene oxide compound solution, and standing for 6-30 hours to obtain elemental nickel/grapheme nanocomposite material. USE - Method for preparing elemental nickel/graphene nanocomposite material. ADVANTAGE - The method is simple, has convenient operation, and is environment-friendly and highly-effective.
