Novel electrode material based on coral-like cerium orthoferrite (CeFeO3) for efficient alkaline water splitting

Abstract

Nanocrystalline cerium orthoferrite (CeFeO₃), synthesized via a solution combustion method, exhibits a coral-like morphology and single-phase purity. It possesses a low surface area but notable porosity, enabling low overpotentials of −176 mV (HER) and 332 mV (OER). These features indicate its potential as an electrode material for alkaline water splitting (AWS).
