A bismuth-based metal / oxide heterojunction electrode material, a preparation method and application thereof

Abstract

The application discloses a bismuth-based metal / oxide heterojunction electrode material and a preparation method and application thereof, and belongs to the technical field of aqueous battery electrode materials. The bismuth-based metal / oxide heterojunction electrode material is prepared by taking Bi-MOF nanowires as a precursor, performing air calcination treatment, and in-situ oxidation and reduction to form a Bi / Bi2O3 heterojunction. The built-in electric field formed at the interface of the Bi / Bi2O3 heterojunction accelerates charge transfer and oxidation-reduction reaction kinetics, improves the electronic conductivity of the material, and enables the electrode material to have excellent electrochemical rate performance and stability.
