Abstract Electrochemical water splitting is one of the sustainable and clean hydrogen production technologies. Developing active and durable electrocatalysts for enhancing the sluggish oxygen evolution reaction (OER) kinetics remains a formidable challenge. Recently, metal/metal compound heterostructures have been regarded as promising catalysts because of synergistic effects between two components. In particular, the decoration of active catalysts on a sturdy substrate can mitigate the surface deformation and migration of catalysts, which in turn greatly improve the long-term stability of the catalysts. Herein, we report the synthesis of mixed metal sulfide-supported IrNi nanoparticles as electrocatalysts for the OER. The prepared IrNi-based heterostructures exhibit superior activity and stability for the OER as compared to those of commercial Ir/C.
