Advanced Characterization of Proton Exchange Membrane Water Electrolyzers with Spatially‐Resolved X‐Ray Imaging

open access: yesChemCatChem, EarlyView.
This minireview highlights X‐ray imaging tools for investigating proton exchange membrane water electrolyzers at different scales. Spatially and temporally resolved techniques here reported provide essential insights into structural and chemical degradation within all the electrolyzer's components, necessary to bridge the gaps between model systems and

Laser‐Induced Iron Doping of Spinel Thin Film Electrocatalyst: Impact of Pulsed Laser Processing on Surface Cobalt Oxide Doping and Oxygen Evolution Reaction Activity

open access: yesChemCatChem, EarlyView.
Laser‐induced Fe doping of Co3O4 thin films enables pulse‐controlled, depth‐selective modification. Correlating doping profiles with SECCM maps reveals optimal OER activity at intermediate Fe levels, establishing PUDEL as a precise tool for tailoring model electrocatalyst surfaces.

Regulating Interfacial Hydrogen‐Bonding Connectivity by Oxygen Vacancies‐Driven [Fe(CN)6]3− Coordination for Boosting Hydrogen Peroxide Electrosynthesis

open access: yesCarbon Energy, EarlyView.
ABSTRACT The inherent hydroxide‐rich (OH⁻) environment in alkaline media facilitates the two‐electron oxygen reduction reaction (2e−ORR). However, the strong interaction between alkali metal cations and solvated water molecules significantly reduces the connectivity of the hydrogen bond network within the alkaline electric double layer, thereby ...
