Operando and Postmortem Study of Iridium-Decorated Titanium-Based Catalysts in PEM Water Electrolysis

Abstract Understanding the dynamic degradation of oxygen-evolution electrocatalysts under realistic operating conditions is essential for advancing the performance and efficiency of proton exchange membrane (PEM) water electrolyzers. By combining operando Small-Angle and Wide-Ang...

Different Conditions, Different Composition: Reactive Environment-Induced Surface Composition Dynamics in Pt-Based Bimetallic Alloys

Abstract Due to their unique properties, bimetallic platinum-based alloys often exhibit superior activity compared to their parent counterparts for many catalytic reactions. Nevertheless, as multimetallic systems, they often undergo compositional and structural changes under reac...
