Synthesis of Ni_4.5Fe_4.5S₈/Ni₃S₂ film on Ni₃Fe alloy foam as an excellent electrocatalyst for the oxygen evolution reaction.

ABSTRACT: Directly synthesizing bicomponent electrocatalysts in the nanostructured form from bulk alloy foam has many potential advantages: robust stability, synergistic effects and fast electron transfer. Here, Ni_4.5Fe_4.5S₈/Ni₃S₂ film with micrometer thickness on bulk substrate was synthesized by a simple one-step hydrothermally assisted sulfurization of Ni₃Fe alloy foam for the oxygen evolution reaction (OER) in basic media. Benefiting from the synergetic effect of the bicomponent, reduced interfacial resistance between electrocatalyst and metal substrate, and more exposed catalytic sites on the microstructured film, the as-prepared electrocatalyst (Ni_4.5Fe_4.5S₈/Ni₃S₂‖Ni_3</
