▎ 摘　　要

NOVELTY - A metal-organic framework (MOF)-graphene/foam nickel composite material comprises foam nickel as framework, reduced graphene oxide in-situ grown in the foam nickel surface and internal pores, and the foam nickel and reducing graphene oxide surface and pore is covered with MOF material. The MOF material is at least one of zeolite imidazole ester framework structure material, lavatin framework material, and coordinated pillared layered material with a particle size of 100 nm-50 nu m and a thickness of 1 nm-1 mu m. USE - The composite material is used as electrode material for electrocatalytic water oxygen evolution. ADVANTAGE - The composite material improves active site exposure, mass transfer and electronic transmission, can be repeatedly used without recycling; and has strong practicability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the metal organic framework-graphene/foam nickel composite material.
