Hydrogen energy is a sustainable and clean source that can meet global demands without adverse environmental impacts. High-entropy oxides (HEOs), multielement (5 or more) with an equiatomic near-equatomic elemental composition, offer novel approach to designing bifunctional electrocatalysts. This work explores (ZnNiCoFeY)xOy over MoS2 as electrocatalyst (HEO-MoS2) in alkaline medium. The HEO was synthesized using combustion process loaded ultrasonic method. exhibits excellent performance, including long-term stability for 24 hours, overpotential of 214 mV vs the reversible hydrogen electrode (RHE) evolution reaction (HER), 308 oxygen (OER) at 10 mA cm−2. low both HER OER high current densities. Additionally, HEO-MoS2 demonstrates smaller solution charge transfer resistance values. electrolyzer assembled electrodes overall water splitting. These exhibited cell voltage 1.65 V fabricated facile scalable method appeals industrial applications.
