Octahedral Ru Centers Modulate Lattice Covalency and Interfacial PCET for Stable Acidic Oxygen Evolution.
Developing active and durable catalysts for acidic oxygen evolution reaction (OER) is critical for proton-exchange membrane water electrolysis (PEMWE). However, it remains challenging because highly active oxides often undergo over-oxidation and structural degradation under anodic conditions. In this study, we report a...
