Abstract Hydrogen production by electrochemical water splitting is considered to be a key strategic energy technology, and proton exchange membrane electrolyzers (PEMWEs) anion (AEMWEs) are ideal technologies for green hydrogen in recent years. However, PEMWEs AEMWEs lack low‐cost high‐performance acidic oxygen evolution reaction (OER) alkaline (HER) electrocatalysts respectively, limiting their large‐scale development. Recently, ruthenium (Ru)‐based have received lot of attention because activity better than that commercial catalysts price more affordable, showing great potential OER HER. there still obstacles Ru‐based practical applications industrial electrolyzers, regulatory strategies need developed further optimize its performance. Herein, comprehensive review presented concerning it. First, fundamental principles focus the basic content application discussed. Then, summarized, providing detailed analysis elucidate mechanisms, properties, electrolyzers. Finally, outlooks prospects challenges future proposed.

Selenium‐Mediated Sub‐1 nm Amorphous Shell Spatially Confines Platinum Nanocrystal for Efficient Hydrogen Evolution

Abstract Ultrafine nanocatalysts can provide abundant catalytic sites, but typically it is less stable and susceptible to dissolution diffusion. Here, this work reports a selenium‐mediated strategy construct sub‐nanometers amorphous shell on ultrafine Pt nanocrystal core, forming Pt@PtSe x core/shell nanostructure. In developed strategy, the active Se‐oleylamine precursor after nucleation confines overgrowth oriented attachment of Pt, allowing in situ formation nanostructures combining size sub‐nano shell. Essentially, PtSe not only optimize hydrogen adsorption energy lower water dissociation energy, also retard atoms, thus leading significantly improved activity durability both acidic alkaline electrolytes. The overall splitting be driven by small cell voltage 1.48/1.53 V at 10 mA cm −2 0.5 M H 2 SO 4 /1.0 KOH, respectively. Moreover, ‐1 with ≈0.8 nm thick exhibits ultra‐high mass 75.2 A mg −1 18.4 −70 mV, as well robust operation for 1100 h 100 (1300 160 acidic), superior most reported Pt‐based electrocatalysts.

Distribution of Oxygen Vacancies in RuO₂ Catalysts and Their Roles in Activity and Stability in Acidic Oxygen Evolution Reaction

The Journal of Physical Chemistry Letters, Год журнала: 2025, Номер unknown, С. 5418 - 5428

By combining density functional theory (DFT) calculations and the cluster expansion (CE) model in an active-learning framework, we comprehensively studied distribution features of oxygen vacancies (OV's) as well their contributions to stability activity RuO2 catalyst acidic evolution reaction (OER). The results show that OV's prefer be located at bridge sites on RuO2(110) surface next-nearest-neighbor trans positions RuO6 octahedra pairs due interactions between two OV's, high concentrations exhibit a continuous zigzag (110) plane RuO2. vacancy can explained by charge repulsion low-valent Ru O, which is referred "heterovalent ion-oxygen exclusion principle". In addition, DFT presence cannot improve inherent OER specific since hinder deprotonation second water molecule. Nevertheless, suppressing lattice mechanism (LOM) path. summary, this work provides deeper insights into with media possible way performance using engineering.
