Abstract

Single‐atom catalysts (SACs) have exhibited high activities for the hydrogen evolution reaction (HER) electrocatalysis in acidic or alkaline media, when they are used with binders on cathodes. However, to date, no SACs have been reported for the HER electrocatalysis in neutral media. We demonstrate a potential‐cycling method to synthesize a catalyst comprising single Pt atoms on CoP‐based nanotube arrays supported by a Ni foam, termed PtSA‐NT‐NF. This binder‐free catalyst is centimeter‐scale and scalable. It is directly used as HER cathodes, whose performances at low and high current densities in phosphate buffer solutions (pH 7.2) are comparable to and better than, respectively, those of commercial Pt/C. The Pt mass activity of PtSA‐NT‐NF is 4 times of that of Pt/C, and its electrocatalytic stability is also better than that of Pt/C. This work provides a large‐scale production strategy for binder‐free Pt SAC electrodes for efficient HER in neutral media.

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?

  • Pt single atoms and Pt clusters coexist on the surface of the Pt@MC-VA electrode.

    “As previously reported, these results indicate that Pt single atoms and Pt clusters coexist on the surface of the Pt@MC-VA electrode [13,33].”

    From Vertically aligned Pt/MXene/carbon nanotubes aerogels for superior hydrogen evolution reaction (2024) · cites this paper as [13]

    The paper’s concluding passage says its PtSA‐NT‐NF catalyst contains single Pt atoms without Pt grains or particles. Its microscopy discussion likewise reports no Pt crystal grains or particles. It studies PtSA‐NT‐NF, not Pt@MC-VA, and does not report the attributed coexistence of single atoms and clusters. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

    Experimental — accuracy not yet measured
  • The better low-overpotential HER performance of commercial Pt/C compared to Pt@MC-VA is due to its much higher noble metal content (20 wt%).

    “due to its much higher noble metal content (20 wt%) [13].”

    From Vertically aligned Pt/MXene/carbon nanotubes aerogels for superior hydrogen evolution reaction (2024) · cites this paper as [13]

    The paper identifies commercial Pt/C as 20 wt% Pt and reports lower overpotential for it than for the paper’s PtSA‐NT‐NF catalyst at 10 mA cm−2 (Figure 3 caption and Figure 4 discussion; page unavailable). It does not study Pt@MC-VA or establish that higher Pt content causes the claimed performance difference. (LLM, conf=0.87)

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.
