Effect of Saturating the Electrolyte with Oxygen on the Activity for the Oxygen Evolution Reaction [PDF]

open access: yesACS Catalysis, 2018
With the increased interest in the electrochemical conversion of renewable electricity, water, and carbon dioxide to fuels, there is an ever-growing number of papers reporting new electrocatalysts for the oxygen evolution reaction (OER).1−5 The OER is the anode reaction in the electrolysis of water and CO2 and a major source of efficiency loss, because

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

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.
