However, chloride ions compete through parasitic reactions, such as the chlorine evolution reaction, creating a serious challenge that reduces catalytic activity and durability. Herein, a hybrid electrocatalyst composed of FeCoS embedded in a polyaniline matrix (FCS-PANI) is synthesized using a simple hydrothermal method. This fabricated composite combines the benefits of the high catalytic activity of FeCoS and the corrosion resistance of the conductive polymer (PANI). Structural analysis establishes the formation of a uniform nanocomposite with strong metalsulfur and metalnitrogen interactions. Advanced oxygen evolution reaction (OER) performance with a low overpotential of 327?mV at 30?mA?cm?2 and a Tafel slope of 38.67?mV dec?1 is achieved through electrochemical testing in alkaline seawater. High stability, low degradation (0.3?mV?h?1) over 500?h of operation, and 99.97% hydrogen purity are observed upon integration into an anion exchange membrane water electrolyzer (AEMWE), indicating its practical potential for seawater electrolysis. 2026 Elsevier B.V.
