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 Integrating active sites for oxygen reduction and evolution reactions (ORR OER) is pivotal advancing bifunctional electrodes. Addressing the geometric/electronic properties of these essential to disrupt linear scaling relationship between adsorption desorption complex intermediates. Herein, a proof‐of‐concept presented constructing asymmetric trinuclear employing both composition‐ size‐based coupling strategies. These comprise ORR‐active Fe single atom (Fe SA ), OER‐active atomically clustered species AC Ni as modulators. This AC‐SA ‐Ni @N‐doped carbon exhibits excellent catalytic activities, with narrow potential gap 0.661 V an ORR half‐wave 0.931 OER 1.592 at 10 mA cm −2 . The Zn‐air battery this material achieves peak power density 293 mW , specific capacity 748 mAh g Zn −1 remarkable stability. Experimental findings theoretical simulations reveal that induced strong electronic among centers, facilitating charge redistribution optimizing barriers enhances rapid release * OH during efficient transformation from O OOH OER. study presents novel strategy developing robust

Academician Tao Zhang and co‐workers designed prepared the first Pt 1 /FeO x “single‐atom catalysts (SACs)” in 2011, which fills gap between homogeneous catalysis heterogeneous catalysis. The “single‐cluster (SCCs)” (e.g., triatomic clusters multiatomic clusters) with continuous metal sites fully exposed atomic structures exhibit unique synergistic effects high catalytic efficiencies. SACs SCCs can undergo dynamic structural evolution both geometric electronic actual conditions. of two atomic‐level presents great opportunities challenges for real mechanism stability. Herein, a new concept “dynamic (DCSs)” is proposed to illuminate these phenomena fields. Particularly, DCSs are divided into three categories: 1) structures, 2) coordinated 3) structures. scientific significances application principles versatile fields (including thermocatalysis, photocatalysis, electrocatalysis) summarized. underlying rational proposals also provided this perspective review.
