Abstract

Development of single-atomic-site catalysts with high metal loading is highly desirable but proved to be very challenging. Although utilizing defects on supports to stabilize independent metal atoms has become a powerful method to fabricate single-atomic-site catalysts, little attention has been devoted to cation vacancy defects. Here we report a nickel hydroxide nanoboard with abundant Ni 2+ vacancy defects serving as the practical support to achieve a single-atomic-site Pt catalyst (Pt 1 /Ni(OH) x ) containing Pt up to 2.3 wt% just by a simple wet impregnation method. The Ni 2+ vacancies are found to have strong stabilizing effect of single-atomic Pt species, which is determined by X-ray absorption spectrometry analyses and density functional theory calculations. This Pt 1 /Ni(OH) x catalyst shows a high catalytic efficiency in diboration of a variety of alkynes and alkenes, yielding an overall turnover frequency value upon reaction completion for phenylacetylene of ~3000 h −1 , which is much higher than other reported heterogeneous catalysts.

  • Loading Pt onto substrates with large specific surface areas is an effective solution to inhibit Pt aggregation.

    “Loading Pt onto substrates with large specific surface areas (e.g., lamellar Ni(OH)2 [13], Ni2P aerogel [14], and Mxene [15]) is an effective solution to inhibit Pt aggregation.”

    From Synergistic interaction of monodisperse Pt nanoparticles with defect‐rich graphene aerogel for efficient acidic hydrogen evolution (2025) · cites this paper as [13]

    The Results report that Pt remained isolated on Ni(OH)x nanoboards, supporting the use of this nickel-hydroxide substrate as an example. But the Discussion attributes the prevention of Pt aggregation to Ni²⁺ vacancies and stronger Pt–support interactions, not to a large specific surface area; Pt nanoparticles formed on the comparison Ni(OH)2 support.

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.
