Oxygen evolution electrode material and preparation method and application thereof

The invention provides an oxygen evolution electrode material and a preparation method and application thereof, and the preparation method comprises the following steps: S1, taking foamed nickel for pretreatment to obtain pretreated foamed nickel; s2, taking a reference electrode, a counter electrode and the pretreated foamed nickel as working electrodes, putting the working electrodes into an electrolyte containing nickel salt and iron salt, and performing constant-current electrodeposition under constant current to obtain an oxygen evolution electrode material precursor; and S3, taking the precursors of the reference electrode, the counter electrode and the oxygen evolution electrode as working electrodes, and carrying out constant-voltage electrodeposition in an electrolyte containing phosphate and sulfate under a constant voltage to obtain the oxygen evolution electrode material. The oxygen evolution electrode material obtained by adopting the preparation method disclosed by the invention has relatively h
