Abstract

High-efficiency electrochemical hydrogen evolution reaction (HER) offers a promising strategy to address energy and environmental crisis. Platinum is the most effective electrocatalyst for the HER. However, challenging scarcity, valuableness, and poor electrochemical stability still hinder its wide application. Here, we designed an outstanding HER electrocatalyst, highly dispersed rhodium (Rh) nanoparticles with an average diameter of only 3 nm supported on boron (B) nanosheets. The HER catalytic activity is even comparable to that of commercial platinum catalysts, with an overpotential of only 66 mV in 0.5 M H 2 SO 4 and 101 mV in 1 M KOH to reach the current density of 10 mA cm −2 . Meanwhile, the catalyst exhibited impressive electrochemical durability during long-term electrochemical processes in acidic and alkaline media, even the simulated seawater environment. Theoretical calculations unraveled that the structure–activity relationship between B(104) crystal plane and Rh(111) crystal plane is beneficial to the release of hydrogen, and surface O plays a vital role in the catalysis process. Our work may gain insights into the development of supported metal catalysts with robust catalytic performance through precise engineering of the strong metal-supported interaction effect.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Weak binding between loaded metals and carbon supports often results in agglomeration of active species, diminishing atomic utilization.

    “Carbon supports have found widespread use”

    From Poison-proofing platinum nanocatalysts with nitrogen for industrial-scale seawater splitting (2026) · cites this paper as [20]

    The Introduction (page unavailable) says metal atoms tend to agglomerate because of their high surface free energy, limiting theoretical atom utilization. It also says porous carbon supports do not achieve complete participation of metal active sites. It does not say that weak binding between metals and carbon supports causes the agglomeration.

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.
