Randomized trial demonstrates HER suppression in P-doped WO3 catalysts, suggesting a new doping mechanism.

This research aims to uncover the mechanisms by which phosphorus doping in tungsten oxide suppresses the hydrogen evolution reaction (HER).
Employed electrochemical impedance spectroscopy to analyze charge transfer properties.
Conducted Mott–Schottky analysis for electronic structure evaluation.
Utilized density functional theory calculations to investigate hydrogen binding interactions.
Phosphorus doping increases adsorption resistance, significantly reducing HER kinetics.
Higher P-doping levels correlate with stronger suppression of proton intercalation and HER.
Doping broadens hydrogen binding strength distribution, leading to weak binding at many sites, limiting proton intercalation.

Kucukosman et al. (2026) studied this question.
