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

Cation Overcrowding Effect on the Oxygen Evolution Reaction [PDF]
JACS Au, 2021 The influence of electrolyte ions on the catalytic activity of electrode/electrolyte interfaces is a controversial topic for many electrocatalytic reactions. Herein, we focus on an effect that is usually neglected, namely, how the local reaction conditions are shaped by nonspecifically adsorbed cations. We scrutinize the oxygen evolution reaction (OER)

A Bifunctional Electrocatalyst for Oxygen Evolution and Oxygen Reduction Reactions in Water [PDF]
Angewandte Chemie International Edition, 2016 AbstractOxygen reduction and water oxidation are two key processes in fuel cell applications. The oxidation of water to dioxygen is a 4 H+/4 e− process, while oxygen can be fully reduced to water by a 4 e−/4 H+ process or partially reduced by fewer electrons to reactive oxygen species such as H2O2 and O2−.
