Classification: CPC C  Y | IPC C

Claim 5:
6. A preparation method of the W18O49/CoO/NF self-supporting electrocatalytic material according to claim 1, comprising:
(1) draining a first solution containing a cobalt source into a second solution containing a tungsten source during a stirring process to obtain a third solution;
(2) putting the foamed nickel into a high-pressure reaction kettle containing the third solution reacting at 120 to 220° C. for 1 to 36 hours, and then washing and drying to obtain the foamed nickel grown with a precursor of W18O49/CoO; and
(3) calcining the foamed nickel grown with the precursor of W18O49/CoO in a nitrogen atmosphere at 200 to 400° C. to obtain the W18O49/CoO/NF self-supporting electrocatalytic material.
