Structurally Ordered Pt3Co Nanoparticles Anchored on N-Doped Graphene for Highly Efficient Hydrogen Evolution Reaction
Abstract
Developing highly efficient catalysts for hydrogen evolution reaction (HER) play a significant role in the large-scale application of electrochemical water splitting. Here, we develop an ultrafine ordered Pt 3 Co NPs supported on N-doped graphene (NG), which achieves high HER activity with a small overpotential of 13 mV at 10 mA cm –2 . More importantly, at the overpotential of 20 mV, the ordered Pt 3 Co catalyst (Pt 3 Co/NG-700) indicates 19.0 and 51.8 times mass activity than that of the disordered Pt 3 Co catalyst (Pt 3 Co/NG) and commercialized Pt/C catalyst, respectively. Additionally, the Pt 3 Co/NG-700 electrocatalyst displays outstanding long-term stability under harsh chronopotentiometry and cycling tests in the acidic media. The theory calculations reveal that the extraordinary HER performance on Pt 3 Co/NG-700 electrocatalyst originates from the charge redistribution of Pt induced by Co in the structurally ordered Pt 3 Co intermetallic. The charge redistribution of Pt facilitates the adsorption and dissociation of H* and provides a higher electron transfer and better conductivity, resulting in high HER. Our work opens new opportunities to design noble based alloy catalysts for highly efficient HER.

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.
