The development of efficient and stable electrocatalysts for the hydrogen evolution reaction (HER) is essential realization effective production via seawater electrolysis. Herein, study has developed a simple method that combines electrospinning with subsequent thermal shock technology to effectively disperse ruthenium nanoparticles onto highly conductive titanium carbide nanofibers (Ru@TiC). electronic metal-support interactions (EMSI) resulted from charge redistribution at interface between Ru TiC support can optimize desorption kinetics sites induce spillover phenomenon, thereby improving evolution. As result, Ru@TiC catalyst exhibits outstanding HER activity, requiring low overpotentials only 65 mV in alkaline current density 100 mA cm-2. Meanwhile, demonstrates excellent stability, maintaining consistent operation 500 cm-2 least 250 hours. Additionally, an anion exchange membrane electrolyzer incorporating operated continuously over hours 200 seawater. This highlights significant potential robust supports fabrication enduring enhance complex environments.

Abstract Zn‐Co/air hybrid batteries showcase enhanced energy efficiency, power density, and stability compared to Zn‐air batteries. Nevertheless, it remains challenging fabricate multi‐functional cathode materials with fast reaction kinetics. Herein the synthesis of a wheat‐like composed “cereal‐grains” densely arranged Co/Co 2 P heterostructures grown on “central stems” P/N codoped carbon nanofibers (denoted as P@PNCF) is presented. The biomimetic nanostructures not only offer abundant exposed active sites maximize accessibility but also establish efficient multi‐channel networks for both electron transfer O /OH − diffusion. Furthermore, species high‐valent Co, resulting from self‐reconstruction heterojunction during first cycle, create Co 2+ ↔ 4+ redox pairs provide additional charging‐discharging voltage plateaus. In situ Raman spectroscopy measurement combined ex X‐ray diffraction evidence supports reversible process 3+/4+ x (OH) y K 2+/3+ , leading improved efficiency durability battery. As result, battery based P@PNCF exhibits remarkable density (321 mW cm −2 ), ultralong cycle (700 h), large (62% at 20 mA ).
