Hydrogen, derived from water splitting, holds promise as a sustainable energy carrier. However, replacing fossil fuels demands large volumes of pure water, resource that is scarce in numerous regions globally. This study focuses on developing an efficient electrocatalyst for seawater aiming to conserve freshwater resources and overcome the challenges associated with direct utilization seawater. Zinc iron layered double hydroxides combined nickel cobalt sulfides foam (ZnFe LDH@NiCoS/NF) are produced operate efficiently alkaline which involves evolution reactions hydrogen oxygen. Through alkalinized electrolyte suitable substrates, adverse effects corrosion chlorine oxidation effectively mitigated.

Abstract Alkaline electrolysis plays a crucial role in sustainable energy solutions by utilizing electrolytic cells to produce hydrogen gas, providing clean and efficient method for storage conversion. Efficient, stable, low‐cost electrocatalysts the oxygen evolution reaction (OER) are essential facilitate alkaline water on commercial scale. Nickel‐iron‐based (NiFe‐based) transition metal considered most promising non‐precious catalysts OER due their low cost, abundance, tunable catalytic properties. Nevertheless, majority of existing NiFe‐based suffer from limited activity poor stability, posing significant challenge meeting industrial applications. This also highlights common situation where emphasis material receives attention, while equally critical stability aspect is often underemphasized. Initiating with comprehensive exploration materials, this article first summarizes debate surrounding determination active sites electrocatalysts. Subsequently, degradation mechanisms recently reported outlined, encompassing assessments both chemical mechanical endurance, along approaches enhancing stability. Finally, suggestions put forth regarding considerations design electrocatalysts, focus heightened
