Abstract Developing low‐cost and highly efficient earth‐abundant oxygen evolution reaction (OER) electrocatalysts via an energy‐ time‐saving method is of great significance to the generation H 2 from electrochemical water splitting, which desirable but still challenging. Herein, a one‐step route in situ grow S‐doped FeOOH vertical nanosheets on iron foam (IF) 20 min under room temperature shown. This facile ultrafast effectively modifies surface IF into layer, full‐Fe electrode (S‐FeOOH/IF) achieved. Systematic experiments characterizations demonstrate that redox reactivities for both lattice are sufficiently activated, leading dramatically improved intrinsic OER activity. The as‐obtained S‐FeOOH/IF exhibits fascinating performance with low overpotential 244 at 10 mA cm −2 . work affords engineering strategy drive commercial cost‐efficient robust oxidation, has important implications clean production through low‐carbon environmentally friendly route.

Abstract Direct seawater electrolysis is proposed as a potential low‐cost approach to green hydrogen production, taking advantage of the vastly available and large‐scale offshore renewable energy being deployed. However, developing efficient, earth‐abundant electrocatalysts that can survive under harsh corrosive conditions for long time still significant technical challenge. Herein, fabrication self‐supported nickel‐iron phosphosulfide (NiFeSP) nanotube array electrode through two‐step sulfurization/phosphorization reported. The as‐obtained NiFeSP nanotubes comprise abundant NiFeS/NiFeP heterointerfaces under‐coordinated metal sites, exhibiting outstanding activity durability oxygen evolution reactions (HER OER) in simulated alkaline‐seawater solution (KOH + NaCl), with an overpotential 380 (HER) 260 mV (OER) at 500 mA cm ‐2 1000 h. Theoretical calculations support observed performance, showing heterointerface sites synergistically lower barrier rate‐determining step reactions. also shows good catalytic performance urea oxidation reaction (UOR). By coupling UOR HER, bifunctional pair efficiently catalyze overall urea‐mediated alkaline‐saline water 1.938 V h without notable degradation.

Abstract Seawater electrolysis is an innovative technique that can potentially transform hydrogen production and contribute to environmental redemption. However, the lack of good bifunctional electrocatalysts may hinder further development this technology. Herein, nickel hydroxide nanosheets be employed as a precursor producing 3D Prussian blue analogue (PBA) with distinct dimensional structure. Nickel are formed within foam undergo reaction potassium ferricyanide (K 3 [Fe(CN) 6 ]). The structure sheets‐like well‐preserved, containing multitude PBA nanocubes. Following phosphidation at 350 °C, iron‐doped phosphide (Fe‐doped Ni 2 P (1.0 m M ) nanosheets) demonstrates remarkable potential electrocatalyst for total water/seawater splitting. This exceptional performance in overall water splitting, achieving current densities 100 500 mA cm −2 1.0 KOH remarkably low voltages 1.65 2.06 V, respectively. Additionally, its improved ability resist corrosion hydrophilic surface makes it suitable seawater splitting process. material generate KOH, resulting 1.74 2.32 V. These outstanding results, together durability, indicate material's strong practical electrolysis.
