▎ 摘　　要

NOVELTY - Alkaline electrolytic water anode is prepared by utilizing pre-processed conductive substrate to adopt cathode electrochemical deposition method to grow alloy pointed cone array on surface of conductive group, and obtaining alkaline electrolytic water anode comprising conductive base body and alloy tip cone array loaded on surface of conductive base body. The alloy in alloy tip cone array is nickel, cobalt, and/or iron. When alkaline electrolytic water anode is applied to electrolytic water in alkaline electrolyte, oxygen evolution reaction of each alloy pointed cone in alloy pointed cone array and part of alkaline electrolyte contact firstly oxidized to form metal oxide and/or metal hydroxide and/or layered double metal hydroxide (LDH). Then, generating metal hydroxy oxide, and stabilizing metal hydroxy oxide state. The metal hydroxy oxide is active center of oxygen evolution reaction. USE - The alkaline electrolytic water anode is useful for electrolytic water in alkaline electrolyte. ADVANTAGE - The alkaline electrolytic water anode has ultra-high oxygen evolution activity and can work stably for a long time under large current. DETAILED DESCRIPTION - An INDEPENDENTS CLAIM is included for an alkaline electrolytic water anode, prepared by the above method.
