Abstract
This invention discloses a heterogeneous composite electrode material, which uses nickel foam as a carrier and forms a Ni3S2 / MnS heterogeneous composite material with a heterogeneous interface structure on the surface of the nickel foam. Fe is doped into both the Ni3S2 and MnS lattices of the Ni3S2 / MnS heterogeneous composite material. This heterogeneous composite material exhibits good catalytic performance and stability. This invention also provides a method for preparing the heterogeneous composite electrode material, which is simple, suitable for large-scale production, uses low-cost raw materials, and requires simple equipment, making it economical. Furthermore, this invention discloses an application of the above-mentioned heterogeneous composite electrode material in the field of alkaline water electrolysis.
