RuO2-Based Electrocatalysts for Acidic Oxygen Evolution: Mechanistic Origins of the Activity-Stability Trade-Off and Pathways to Rational Design.
Ruthenium dioxide (RuO2) is widely considered as a leading non-iridium candidate for the acidic oxygen evolution reaction (OER) in proton exchange membrane water electrolysis (PEMWE), owing to its high intrinsic activity and comparatively low cost. Its practical implementation, however, is fundamentally limited by a pe...
