P and Mo Dual Doped Ru Ultrasmall Nanoclusters Embedded in P‐Doped Porous Carbon toward Efficient Hydrogen Evolution Reaction
Open accessAbstract
Rational design of efficient hydrogen evolution reaction (HER) electrocatalysts for mass production of hydrogen via electrochemical water splitting is a challenging but pressing task. Herein, an in situ dual doping engineering from phosphomolybdic acid encapsulated within the bimetallic metal‐organic‐frameworks strategy to synthesize P,Mo dual doped Ru ultrasmall nanoparticles embedded in P‐doped porous carbon (P,Mo‐Ru@PC) for efficient HER is proposed. As a result, P,Mo‐Ru@PC achieves a low overpotential of 21 at 10 mA cm −2 , low Tafel slopes of 21.7 mV dec −1 , and a mass activity about 22 times greater than that of commercial 20 wt% Pt/C in alkaline media. First principle calculations demonstrate that introducing Mo and P atoms into Ru lattices triggers the in situ electron donation from Ru to Mo and P and consequently reduces the energy barrier for the 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.
