Vanadium‐Incorporated CoP2 with Lattice Expansion for Highly Efficient Acidic Overall Water Splitting
Abstract
A proton exchange membrane water electrolyzer (PEMWE) in acidic medium is a hopeful scenario for hydrogen production using renewable energy, but the grand challenge lies in substituting noble‐metal catalysts. Herein, a robust electrocatalyst of V−CoP 2 porous nanowires arranged on a carbon cloth is successfully fabricated by incorporating vanadium into the CoP 2 lattice. Structural characterizations and theoretical analysis indicate that lattice expansion of CoP 2 caused by V incorporation results in the upshift of the d‐band center, which is conducive to hydrogen adsorption for boosting the hydrogen evolution reaction (HER). Besides, V promotes surface reconstruction to generate a thicker Co 3 O 4 layer with an oxygen vacancy that enhances acid‐corrosion resistance and optimizes the adsorption of water and oxygen‐containing species, thus improving activity and stability toward the oxygen evolution reaction (OER). Accordingly, it presents a superior acidic overall water splitting activity (1.47 V@10 mA cm−2) to Pt−C/CC||RuO 2/CC (1.59 V@10 mA cm−2), and remarkable stability. This work proposes a new route to design efficient non‐noble metal electrocatalysts for PEMWE.

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.
