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

Self-generation of OH groups on MnO2 surfaces contributes to durability
Abstract
In the CeFeNi4/MnO2/NF heterostructure catalyst, Ce and MnO2 enhance its OER activity. Meanwhile, self-generation of OH groups on MnO2 surfaces prevents catalyst corrosion in alkaline seawater.
