Valence Oscillation of Ru Active Sites for Efficient and Robust Acidic Water Oxidation
Open accessAbstract
The continuous oxidation and leachability of active sites in Ru‐based catalysts hinder practical application in proton‐exchange membrane water electrolyzers (PEMWE). Herein, robust inter‐doped tungsten–ruthenium oxide heterostructures [(Ru–W)Ox] fabricated by sequential rapid oxidation and metal thermomigration processes are proposed to enhance the activity and stability of acidic oxygen evolution reaction (OER). The introduction of high‐valent W species induces the valence oscillation of the Ru sites during OER, facilitating the cyclic transition of the active metal oxidation states and maintaining the continuous operation of the active sites. The preferential oxidation of W species and electronic gain of Ru sites in the inter‐doped heterostructure significantly stabilize RuOx on WOx substrates beyond the Pourbaix stability limit of bare RuO 2. Furthermore, the asymmetric Ru–O–W active units are generated around the heterostructure interface to adsorb the oxygen intermediates synergistically, enhancing the intrinsic OER activity. Consequently, the inter‐doped (Ru–W)Ox heterostructures not only demonstrate an overpotential of 170 mV at 10 mA cm−2 and excellent stability of 300 h in acidic electrolytes but also exhibit the potential for practical applications, as evidenced by the stable operation at 0.5 A cm−2 for 300 h in 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.
