Solution-phase epitaxial growth of noble metal nanostructures on dispersible single-layer molybdenum disulfide nanosheets
Open accessAbstract
Compared with the conventional deposition techniques used for the epitaxial growth of metallic structures on a bulk substrate, wet-chemical synthesis based on the dispersible template offers several advantages, including relatively low cost, high throughput, and the capability to prepare metal nanostructures with controllable size and morphology. Here we demonstrate that the solution-processable two-dimensional MoS(2) nanosheet can be used to direct the epitaxial growth of Pd, Pt and Ag nanostructures at ambient conditions. These nanostructures show the major (111) and (101) orientations on the MoS(2)(001) surface. Importantly, the Pt-MoS(2) hybrid nanomaterials exhibit much higher electrocatalytic activity towards the hydrogen evolution reaction compared with the commercial Pt catalysts with the same Pt loading. We believe that nanosheet-templated epitaxial growth of nanostructures via wet-chemical reaction is a promising strategy towards the facile and high-yield production of novel functional materials.

After loading a certain amount of noble-metal nanoparticles, the composite catalyst showed excellent HER performance and higher stability compared to the commercial Pt-C catalyst.
“After loading a certain amount of noble-metal nanoparticles, the composite catalyst showed excellent HER performance and higher stability compared to the commercial Pt-C catalyst. [ 56,57 ]”
From 2D Transition‐Metal‐Dichalcogenide‐Nanosheet‐Based Composites for Photocatalytic and Electrocatalytic Hydrogen Evolution Reactions (2016) · cites this paper as [56]
The section ‘Electrocatalytic activity of Pt-MoS2 nanomaterials for HER’ reports excellent HER activity for Pt nanoparticles on MoS2 and a higher current density than commercial Pt-C at equal Pt loading. Neither that section nor the retrieved passages report a stability comparison, so the claim of higher stability is unsupported. (LLM, conf=0.88)
Experimental — accuracy not yet measuredNoble metal nanocrystals (Au, Ag, Pt, Pd) can grow on the surface of single-layer MoS2 nanosheets by using reduction agents or photochemical reduction.
“Recently, our group has demonstrated that a series of noble metal nanocrystals (Au, Ag, Pt, and Pd) could grow on the surface of single-layer MoS 2 nanosheets by using reduction agents (e.g., ascorbic acid) or the photochemical reduction method. [ 56 ]”
From 2D Transition‐Metal‐Dichalcogenide‐Nanosheet‐Based Composites for Photocatalytic and Electrocatalytic Hydrogen Evolution Reactions (2016) · cites this paper as [56]
The introduction and the section “Epitaxial growth of Pd, Pt and Ag NSs on MoS₂ nanosheets” report growth of Au, Ag, Pt and Pd nanostructures on single-layer MoS₂. That section lists chemical and photochemical reduction among the methods used, but says Au deposited spontaneously without an added reducing agent; the claim omits this third route. Page numbers are not provided in our copy. (LLM, conf=0.88)
Experimental — accuracy not yet measuredThe as-synthesized Pt-MoS2 hybrid exhibited excellent electrocatalytic activity towards HER with near-zero overpotential and Tafel slope of 40 mV per decade, comparable with commercial Pt-C catalysts.

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.
