The invention discloses a preparation and application of a graphene based metal compound nano array material, and belongs to the technical field of preparation of functional nano materials. A carbon precursor and a metal salt mixture are ground and then coat a foam nickel substrate, the coated foam nickel substrate is subjected to heat treatment in an inert atmosphere, and a graphene array material is obtained by washing. The graphene based metal compound nano array material is obtained from the graphene array material by solution growth or electrochemical deposition and calcination and other ways. The nano array material prepared by the method has high electric conductivity, fast ion transfer channels, high active sites and other physical properties, and shows electricity storage performance of long service life and high capacity and excellent electrochemical catalytic activity and stability in energy storage and conversion and electrochemical catalysis reactions. The whole material preparation process is simple, no toxic products are generated in the reaction, and the preparation method has the advantages of low energy consumption, and green and environmental protection, and is suitable for large-scale industrial production.
