Abstract: The invention discloses a self-derivative iron-containing nickel anode for alkaline water electrolysis and its preparation method. The anode comprises a nickel substrate and catalytic material layer. The catalytic layer is disposed on and integrated with the surface of the nickel substrate. The catalytic layer contains nickel oxide with iron components. The nickel oxide results from the reaction of the surface layer of the nickel substrate with an oxidant-rich alkaline solution and forms a nanosheet array layer. A nickel-oxidation state containing the iron component is formed by electrochemically induced iron-ion corrosion of the nickel-oxidation state. The invention can effectively reduce the potential difference between the anode and cathode of an electrolysis cell, thereby significantly reduces energy consumption and improves the efficiency of water electrolysis.
