Gold-Triggered Restructuring of Interfacial Water on Ir Nanoclusters Switches Oxygen Evolution Pathways toward Stable Acidic Electrocatalysis
Ir-based anodes for proton exchange membrane water electrolysis (PEMWE) often degrade when lattice oxygen participates in acidic OER, accelerating Ir dissolution. Here, we engineer the interfacial water microenvironment by alloying Au with low-crystallinity Ir nanoclusters on TiO2 (IrAu0.12@TiO2). The Ir-Au work-func...
