A Sustainable Route to Ruthenium Phosphide (RuP)/Ru Heterostructures with Electron‐Shuttling of Interfacial Ru for Efficient Hydrogen Evolution
Open accessAbstract
Ruthenium (Ru) is a promising electrocatalyst for the hydrogen evolution reaction (HER), despite suffering from low activity in non‐acidic conditions due to the high kinetic energy barrier of H 2 O dissociation. Herein, the synthesis of carbon nanosheet‐supported RuP/Ru heterostructures (RuP/Ru@CNS) from a natural polysaccharide is reported and demonstrates its behavior as an effective HER electrocatalyst in non‐acidic conditions. The RuP/Ru@CNS exhibits low overpotential (106 mV at 200 mA·cm −2 ) in alkaline electrolyte, exceeding most reported Ru‐based electrocatalysts. The electron shuttling between Ru atoms at the RuP/Ru interface results in a lowered energy barrier for H 2 O dissociation by electron‐deficient Ru atoms in the pure Ru phase, as well as optimized H * adsorption of electron‐gaining Ru atoms in the neighboring RuP. A low H * spillover energy barrier between Ru atoms at the RuP/Ru interface further boosts HER kinetics. This study demonstrates a sustainable method for the fabrication of efficient Ru‐based electrocatalysts and provides a more detailed understanding of interface effects in HER catalysis.

Ruthenium is a compelling alternative to Pt for hydrogen production due to its relatively lower cost, favorable hydrogen adsorption energy, and well-established catalytic performance.
“ruthenium (Ru) has emerged as a compelling alternative to Pt for hydrogen production due to its relatively lower cost, favorable hydrogen adsorption energy, and well-established catalytic performance [8–12].”
From Efficient Hydrogen Evolution Catalysis Enabled by Ru Nanoparticles on Few‐Layer Black Phosphorus/Graphene Heterostructured Aerogels (2026) · cites this paper as [10]
The Introduction (page unavailable) calls Ru catalysts promising for hydrogen evolution and describes their extensive study, supporting the claim about established catalytic performance. It does not establish that Ru costs less than Pt. The Results and Discussion (page unavailable) finds that pure Ru binds hydrogen strongly, making H₂ desorption difficult; more favorable adsorption behavior is achieved in the engineered RuP/Ru heterostructure, not attributed to Ru generally.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
