Abstract Benefiting from similar hydrogen bonding energy to Pt and much lower price compare with Pt, Ru based catalysts are promising candidates for electrocatalytic evolution reaction (HER). The catalytic activity of nanoparticles can be enhanced through improving their dispersion by using different supports, the strong metal supports interaction further regulate performance. In addition, single‐atom (SACs) almost 100% atomic utilization attract great attention coordinative atmosphere single atoms adjusted supports. Moreover, syngenetic effects improve performance catalysts. this review, progress HER electrocatalysts summarized according existing forms, including (NPs), (SAs) combination both NPs SAs. common such as carbon materials, oxides, phosphides sulfides classified clarify active centers. Especially, possible mechanisms reasons improved discussed experimental results theoretical calculations. Finally, some challenges opportunities prospected facilitate development HER.

ABSTRACT Ruthenium (Ru)‐based electrocatalysts show great promise as substitutes for platinum (Pt) the alkaline hydrogen evolution reaction (HER) because of their efficient water dissociation capabilities. Nevertheless, strong adsorption Ru–OH intermediates (Ru‐OH ad ) blocks active site, leading to unsatisfactory HER performance. In this study, we report a universal ligand‐exchange strategy synthesizing MOF‐on‐MOF‐derived FeP–CoP heterostructure‐anchored Ru single‐atom site catalyst (Ru‐FeP‐CoP/NPC). The obtained shows low overpotential (28 mV at 10 mA cm −2 and high mass activity (9.29 A mg −1 100 mV), surpassing performance commercial Pt/C by factor 46. Theoretical studies that regulating local charge distribution sites could alleviate surrounding OH − blockages, accelerating facilitating adsorption/desorption, thus enhancing activity. This work aims inspire further design highly durable with tailored electronic properties high‐purity production.

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.

Proton exchange membrane (PEM) water electrolyzers are one type of the most promising technologies for efficient, nonpolluting and sustainable production high-purity hydrogen. The anode catalysts account a very large fraction cost in PEM electrolyzer also determine lifetime electrolyzer. To date, Ir- Ru-based materials types acidic oxygen evolution reaction (OER), but they still face challenges high or low stability. Hence, exploring Ir stable electrocatalysts OER attracts extensive research interest recent years. Owing to these great efforts, significant developments have been achieved this field. In review, field comprehensively described. possible mechanisms first presented, followed by introduction criteria evaluation electrocatalysts. development then elucidated according strategies utilized tune catalytic performances. Lastly, future burgeoning is discussed.
