The bifunctional mechanism, involving multiactive compositions to simultaneously dissociate water molecules and optimize intermediate adsorption, has been widely used in the design of catalysts boost electrolysis for sustainable hydrogen energy production but remains debatable due difficulties accurately identifying reaction process. Here, we proposed concept well-defined Lewis pairs single-atom catalysts, with a unique acid-base nature, comprehensively understand exact role an alkaline evolution reaction. By facilely adjusting active moieties, induced synergistic effect between (M-P/S/Cr pairs, M = Ru, Ir, Pt) can significantly facilitate cleavage H-OH bond accelerate removal intermediates, thereby switching rate-determining step from Volmer Heyrovsky step. Moreover, representative Ru-P deliver impressive 266 h durability at high industrial current density 2 A cm-2 without activity decay anion-exchange membrane electrolysis, be extended modify commercial noble-metal-based performance enhancement. This work not only sheds light on important mechanism scale also offers universal descriptor rational advanced catalysts.

Water electrolysis recognizes nickel foam (NF) as an effective current collector due to its excellent conductivity. However, recent studies highlighted NF's effect on the efficacy of various electrocatalytic reactions, primarily presence electroactive chemical species at interface. In contrast, numerous reports suggested that NF has a negligible impact overall activity. When evaluated against other collectors, NF-supported catalysts demonstrate better electrochemical activity, predominantly interfacial design. This study presents electrochemically relevant with flexible design, supported by case and insights into promising future directions. Perspective reveals advantages, challenges, applicability design context water splitting in mind.

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.

Abstract Seawater electrolysis offers a promising pathway to generate green hydrogen, which is crucial for the net-zero emission targets. Indirect seawater severely limited by high energy demands and system complexity, while direct bypasses pre-treatment, offering simpler more cost-effective solution.
