Low-overpotential and chloride-resistant oxygen evolution from alkaline seawater enabled by a synergistic CeFeNi 4 /MnO 2 heterostructure

Key Points

• The research aims to enhance oxygen evolution reaction (OER) efficiency in alkaline seawater using a new heterostructure catalyst.
• Development of a CeFeNi4/MnO2 heterostructure catalyst
• Evaluation of OER activity in alkaline seawater
• Assessment of catalyst corrosion through self-generation of OH groups
• Ce and MnO2 significantly enhance OER activity
• Catalyst demonstrates resistance to corrosion in alkaline conditions
• Self-generation of OH groups on MnO2 surfaces contributes to durability
