Classification: CPC C  Y | IPC C

Claim 5:
6. A preparation method of the W18O49/CoO/CoWO4/NF self-supporting electrocatalytic material according to claim 1, comprising:
(1) dissolving CoWO4 and WCl6 in a solvent to obtain a first solution;
(2) immersing the foamed nickel in an autoclave containing the first solution, and then reacting at 120 to 200° C. for 3 to 36 hours, taking out the foamed nickel, washing, and drying to obtain the foamed nickel with a precursor growing thereon; and
(3) calcining the foamed nickel with the precursor grown at 400 to 500° C. in a nitrogen atmosphere to obtain the W18O49/CoO/CoWO4/NF self-supporting electrocatalytic material.
