Abstract Designing heterogeneous interface to enhance the kinetics for electrocatalysts is a highly efficient but challenging pathway toward hydrogen evolution reaction (HER) in water electrolysis. Herein, coupling of CeO 2 quantum dots onto porous Ru aerogel through interfacial Ru‐O‐Ce bridge proposed construct ‐Ru as superior HER electrocatalyst with ultra‐low overpotentials. In situ characterizations and theoretical calculations reveal electron distribution at boost bonding sites, faster adsorption dissociation sites kinetics. Furthermore, employed excellent cathodes both acidic alkaline electrolyzers ampere‐level current density stably operated over 500 hours. Thus, synergistic effect tunes catalytic mechanism reinforces activity, realizing generation

Abstract Exploring advanced electrolysis techniques for attaining scene‐adaptive and on‐site green H 2 production is an imperative matter of utmost practical significance but grand challenge remains. Herein, drawn inspiration from a spontaneous hydrazine‒H O galvanic cell configured on low‐valence Ru single atoms‐loaded Mo C electrode (Ru SA /v‐Mo C), alternative energy solution utilizing self‐powered electrochemical hydrazine splitting (N 4 → 2H + N ) instead the stereotyped electricity‐consumed water proposed. This highlights pH‐decoupled primary battery with notable open‐circuit voltage 1.37 V density up to 358 Wh g N2H4 −1 , which powerfully propels alkaline cell, leading bilateral harvest remarkable rate 18 mol h m −2 i.e., 403.2 L setting new record self‐sustaining electricity‐powered systems. The success this further decoded by tandem theoretical in situ spectroscopic studies, cross‐verifying Ru‒Mo dual‐site synergy streamlining overall barriers, thereby enhancing kinetics reactions. pioneering work, showcasing free both external feedstock inputs, opens horizon way ultimate solution.

Abstract In‐depth comprehension and improvement of the sluggish hydrogen evolution kinetics in alkaline media is highly important to enhance activity durability anion exchange membrane water electrolysis (AEMWE) for green production. Herein, a atom‐terminated core–shell PdH@Ru nanobamboos (NBs) developed by synergetic strategy epitaxial growth situ DMF hydrogenation. The synthesized NBs demonstrate exceptional reaction (HER) media, requiring only 14 mV overpotential at 10 mA cm −2 , surpassing those commercial Pt/C (35 mV) H‐free Pd@Ru (37 mV). Furthermore, an AEMWE device using as cathode also achieves current density 1000 − 2 ≈1.80 V 1.0 m KOH 60 °C, with continuous operation 50 h. operando spectroscopic analysis functional theory calculations suggest that insertion into induces tensile strain on Ru surface layer, altering Pd/Ru electronic structure weakening H adsorption, thereby enhancing HER efficiency. bamboo‐like hollow features numerous active sites, which contribute optimization electron/mass diffusion electrolyte.
