The present invention belongs to the technical field of electrochemical catalysis. Disclosed are the preparation and use of a nickel-foam-supported layered cobalt tungsten oxide catalyst for efficient water decomposition. In the present invention, nickel foam (NF) is selected as a substrate, on which two cobalt oxides having different morphologies successively grow by means of electrochemical deposition, wherein ComCo3O4 serves as a first layer and can tightly wrap around the NF, thereby preventing the NF from anodic corrosion and dissolution in a harsh acidic medium; AcCo3O4 serves as a second layer, and nanosheet-shaped Co3O4 has good OER activity itself; in addition, the large specific surface area also provides more growth sites for a tungsten oxide; and finally, the tungsten oxide is electrically deposited on the AcCo3O4. WxOy/AcCo3O4/ComCo3O4/NF prepared by using the above method has a low overpotential and good stability.
