ZnS-SnS-NiCo2S4: A New Breakthrough in Quaternary Sulfide Composites for Oxygen Evolution Reaction
Abstract
A ZnS-SnS-NiCo2S4 composite was in situ fabricated on Ni foam by polymetallic compositing of Ni3S2. The optimized catalyst exhibits outstanding OER performance with a low overpotential (149 mV at 10 mA cm-2) and Tafel slope (33.57 mV dec-1), offering a promising strategy for efficient water splitting and sustainable hydrogen production.
