Preparation method of iron-nickel bimetallic selenide nanosphere electrocatalyst

The invention provides a preparation method and application of an efficient iron-nickel bimetallic selenide nanosphere electrocatalyst. The preparation method comprises the following steps: dissolving flaky NaOH in deionized water, stirring until the solution is clear, adding Se powder and N2H4.H2O, stirring, then adding Ni (NO3) 2.6 H2O and Fe (NO3) 3.9 H2O powder, stirring again, centrifuging and washing the obtained turbid liquid through deionized water and absolute ethyl alcohol, and drying in a drying box, so as to obtain the selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium-rich selenium. The obtained product is the efficient iron-nickel bimetallic selenide nanosphere electrocatalyst. Compared with the prior art, the efficient iron-nickel bimetal selenide nanosphere electrocatalyst is prepared, regulated and synthesized in one step throu
