Abstract Developing efficient and long‐lasting electrocatalysts with industrial‐level current densities for seawater splitting is essential electrolysis technology to prevent the unwanted chlorine evolution reaction (CER). In this work, an effective technique of constructing functional interactive catalyst interfaces design bimetallic selenide anchored on 2D MXene (Fe 3 Se 4 /NiSe 2 @MXene) heterostructure fabricated nickel foam. Density‐functional theory (DFT) studies demonstrate that Fe @MXene interface modifies d‐band center electronic structure Ni sites. The coupling effect from heterointerface enhances redistribution charge density improves corrosion‐resistant selenide‐rich passivating layers high activity. demonstrates exceptional performance in 6 m alkaline natural media, achieving 300 360 mV at 500 1000 mA cm −2 industrial densities, respectively, remained durable 250 h 2000 ultra‐high density. Remarkably, electrode as a bifunctional achieves robust stability 140 h. This work inspires optimal catalysts applications.

Abstract The development of robust and efficient electrocatalysts for the oxygen evolution reaction (OER) has been main focus water electrolysis but remains a great challenge. Here, synthesis highly active ultra‐stable Fe‐CoOOH electrocatalyst is reported by steering raw cobalt foam via an in situ solution combustion method assisted galvanic replacement subsequent electrochemical reconstruction CoFeO x pre‐catalyst. In/ ex analysis physicochemical characterizations show that undergoes quick chemical slow morphological to nanosheets. possesses semi‐crystalline nature with distinct short‐range ordering outstanding OER activity overpotentials as low 271 291 mV at current densities 500 1,000 mA cm −2 , respectively. remarkable stability under least 700 h achieved. Theoretical calculations confirm crucial role Fe doping facilitating surface reconstruction, enhancing activity, improving Fe‐CoOOH. Comparative other transition metals reveals unique ability adsorb onto CoOOH surface, thereby modulating electronic density faster adsorption intermediates. This work represents valuable insights into processes.
