Abstract A coupled oxygen evolution mechanism (COM) during oxygen evolution reaction (OER) has been reported in nickel oxyhydroxides (NiOOH)-based materials by realizing e g * band (3d electron states with e g symmetry) broadening and light irradiation. However, the link between the e g * band broad...
