CoP nanowires coupled with CoMoP nanosheets as a highly efficient cooperative catalyst for hydrogen evolution reaction
Abstract
Abstract The rational design and construction of efficient electrocatalysts play a leading role for water splitting, but very rarely Pt-like activity has been obtained by non-noble metal catalysts. It is obvious that the cooperative coupling of non-noble metal catalysts could be regarded as a preferred alternative to Pt-based materials in hydrogen evolution reaction (HER). Herein, a heterostructure electrocatalyst on Ni foam with CoP nanowires coupled with the defective CoMoP nanosheets (CoP/CoMoP) is first synthesized via hydrothermal method followed by low-temperature phosphidation. Results indicate that CoP/CoMoP shows extraordinarily efficient HER activity and robust stability, especially, high activity superior to that of commercial Pt/C in alkaline electrolyte, due to the cooperative effect of interfaces between CoP and CoMoP. Density functional theory (DFT) calculations certified that the interface between the CoP and CoMoP can improve the activity of HER, especially in alkaline condition, by facilitating the H2O-dissociation on the CoMoP and H-adsorption on the CoP. Moreover, the CoMoP with P defects can enhance the activity of HER by preventing the active sites of CoMoP and CoP from the blocking of OH*. It is expected that such heterostructure CoP/CoMoP could provide a powerful interface-engineering strategy to design and construct efficient cooperative electrocatalysts for 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.
