It is essential to develop effective and long-lasting electrocatalysts for seawater splitting prevent the unwanted chlorine evolution reaction withstand corrosive nature of in electrolysis technology. In this study, a unique transition metal catalyst developed enhance splitting. The composed ruthenium (Ru) nanocluster anchored onto nickel-iron diselenide nanosheet arrays grown on nickel foam (Ru-MOF NixFe1-xSe2/NF). Ru metal-organic framework-based Ni Fe heterogeneous catalysts exhibit exceptional performance sustaining high-current-density hydrogen reactions (HERs) oxygen (OERs) during electrolysis. Consequently, OER requires minimal overpotentials 250, 290, 310, 390 mV, while HER needs 130, 199, 189, 315 mV attain current densities 100 500 mA cm-2 1.0 M KOH + natural seawater. Moreover, it maintains stability h at steady density or cm-2. Theoretical calculations indicate that including enhances Gibbs free energy adsorption H2O molecules intermediates HER/OER selenide sites. This optimization leads improved electrocatalytic water/seawater context overall water splitting, composite an both anode cathode, needing voltages 1.61, 1.68, 1.71 V obtain alkaline freshwater, simulated seawater, Particularly, retains consistent test period, indicating promising future practical applications.
