Corrosion-Resistant MoO₃/Fe₂O₃/MoS₂ Heterojunctions Stabilize OH^- Adsorption for Efficient Light-Assisted Seawater Electrooxidation.

ABSTRACT: Direct seawater electrolysis holds promise for sustainable hydrogen production, yet challenges such as severe chlorine corrosion on the anode and high energy barriers for oxygen evolution reaction (OER) limit its operational time and efficiency. Herein, we present MoO₃/Fe₂O₃/MoS₂ heterojunctions to mitigate chlorine-induced corrosion and achieve effective photoelectric synergy. The in situ leached MoO₄^2- and SO₄^2- inhibitors reduce Cl^- adsorption, thereby ensuring high OER selectivity, while the MoO₃/Fe₂O₃/MoS₂ balances the repelling effects of these inhibitors, facilitating OH^- adsorption and widening the overpotential gap between water
