Atomistic Insights into the Electrochemical Oxygen Evolution Activity of Hollandite IrO2 Surfaces
Advanced Science, EarlyView.Lattice distortions at tunnel‐structured hollandite IrO2 surfaces reshape Ir‐O bonding: they weaken the σ‐bond contribution in the Ir‐*OH bond while enhancing the π contribution of the Ir‐*O bond. This orbital reorganization in hollandite surfaces stabilizes *O, facilitates the *OH → O step, and lowers the oxygen‐evolution reaction overpotential ...
