Dec 1, 2019 · RuNi NSs exhibit an outstanding electrocatalytic activity for HER under alkaline conditions (η = 15 mV at 10 mV cm −2). RuNi NSs are highly stable and can undergo 10,000 sweeping cycles with negligible activity decay and structure change.

Mar 7, 2025 · Herein, a heterostructured bimetallic nitrides supported RuNi alloy (RuNi/ZrNiN x) is developed through in situ epitaxial growth under ammonolysis, achieving exceptional bifunctional activity and durability for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in 1 m KOH electrolyte.

Jun 8, 2022 · Herein, a RuNi single atom alloy catalyst was prepared based on a two-step synthesis method including a structural topological transformation of layered double hydroxides (LDHs) followed by a...

Dec 15, 2021 · The optimum 2D RuNi/g-C 3 N 4 photocatalyst with 2.3 wt% Ru elements can reach up to 35,100 umol/g/h for photocatalytic H 2 evolution under simulated sunlight, which is more than 3 times higher than that of the Ru/g-C 3 N 4 sample with the same Ru content.

Aug 21, 2024 · Consequently, RuNi/NC exhibits low overpotential of 12 mV and high durability of 1600 h at 10 mA cm ‒2 for alkaline HER, and demonstrates high performance in both water electrolysis and...

To address this, a RuNi alloy encased within a carbon shell (Ru 0.55 Ni 0.45 @C) is prepared through interchain cross-linking, freeze-drying and carbonization processes. The Ru 0.55 Ni 0.45 @C electrcatalyst demonstrates remarkable HOR activity of 526 A …

Jun 1, 2022 · Here, we establish HOR catalytic activities of single-atom and diatomic sites as a function of *H and *OH binding energies to screen the optimal active sites for the HOR. As a result, the Ru-Ni diatomic one is identified as the best active center.

This holistic work resolves the mechanism of active site separation and strengthening in RuNi alloys, and provides a new design idea for the preparation of highly efficient alkaline HER electrodes.

Hruni (Icelandic pronunciation: [ˈr̥ʏːnɪ]) is a farming village located in the Hrunamannahreppur municipality in the Southern Region, Iceland. [1] The settlement was home to the priest and scholar Árni Halldórsson of Hruni (1630–87). [2]: 171–72. …

Jun 8, 2022 · Herein, a RuNi single atom alloy catalyst was prepared based on a two-step synthesis method including a structural topological transformation of layered double hydroxides (LDHs) followed by a galvanic replacement treatment.
