The Ir–OOOO–Ir Transition State and the Mechanism of the Oxygen Evolution Reaction on IrO2(110) [PDF]

open access: yes, 2022
Carefully assessing the energetics along the pathway of the oxygen evolution reaction (OER), our computational study reveals that the “classical” OER mechanism on the (110) surface of iridium dioxide (IrO2) must be reconsidered.
