Ruthenium (Ru) based catalysts show promise for the hydrogen evolution reaction (HER) due to their cost-effectiveness and catalytic activity. This review covers Ru nanoparticles, single atoms, and their synergistic combinations on various supports.
Area of Science:
- Materials Science
- Electrochemistry
- Catalysis
Background:
- Ruthenium (Ru) catalysts offer a cost-effective alternative to platinum for the electrocatalytic hydrogen evolution reaction (HER).
- Optimizing Ru dispersion on supports and understanding metal-support interactions are key to enhancing catalytic performance.
- Single-atom catalysts (SACs) provide high atomic utilization and tunable coordination environments, further improving efficiency.
Purpose of the Study:
- To review the advancements in Ru-based electrocatalysts for HER.
- To categorize catalysts based on their forms: nanoparticles (NPs), single atoms (SAs), and combined NPs/SAs.
- To analyze the role of various supports in modulating Ru active centers and catalytic mechanisms.
Main Methods:
- Literature review of Ru-based HER electrocatalysts.
- Classification of catalysts based on Ru morphology (NPs, SAs, NPs+SAs).
- Analysis of support materials (carbon, oxides, phosphides, sulfides) and their interactions with Ru.
- Discussion of experimental and theoretical studies on catalytic mechanisms.
Main Results:
- Ru NPs, SAs, and synergistic combinations exhibit enhanced HER activity when appropriately dispersed and supported.
- Support materials significantly influence the electronic structure and coordination environment of Ru active sites.
- Synergistic effects between NPs and SAs can lead to superior catalytic performance compared to individual components.
Conclusions:
- Ru-based catalysts, in various forms and on diverse supports, are highly promising for efficient HER.
- Understanding metal-support interactions and active site coordination is crucial for designing advanced catalysts.
- Further research into challenges and opportunities will accelerate the development of Ru-based HER catalysts.

Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
Reduction of Alkenes: Catalytic Hydrogenation
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
