Fig. 5: Kinetics of Conventional and Water-Mediated O2 Desorption.
From: Oxygen evolution reaction on IrO2(110) is governed by Walden-type mechanisms
a Free-energy diagram of a conventional OER mechanism over the partly hydroxylated IrO2(110) surface at U = 1.53 V vs. RHE. The calculated activation free energy for the desorption of the O2 molecule (1.12 eV) is highlighted in red. b Free-energy diagram of the Walden-type OER mechanism over the partly hydroxylated IrO2(110) surface at U = 1.53 V vs. RHE. The calculated activation free energy for the water-assisted desorption of the O2 molecule (1.05 eV) is highlighted in red.
