FeMoO4 is a stable semiconducting iron-molybdenum oxide used as a catalyst for oxygen-evolution reactions in electrochemical energy systems.
About Iron molybdate
Iron molybdate is a semiconducting oxide that holds a significant position within the family of oxygen-evolution catalysts. As a thermodynamically stable phase located on the convex hull, it exhibits robust structural integrity, making it a reliable candidate for catalytic investigations where material longevity is essential. The compound's electronic nature facilitates charge transfer processes necessary for efficient electrochemical performance.
This material is primarily utilized in research contexts focused on water splitting and energy conversion technologies. Its ability to participate in oxygen-evolution reactions stems from the synergistic interaction between iron and molybdenum centers within the oxide lattice, which helps modulate the catalytic activity required for industrial-scale electrochemical applications.
Key Properties

How It Compares
Within the oxide oxygen-evolution catalysts class.
Unlike the layered lithium-based oxides such as LiCoO2 or LiNiO2 that are frequently employed in battery cathodes, FeMoO4 functions primarily as a stable catalytic oxide. While materials like BiFeO3 or LaMnO3 often feature complex perovskite-derived structures, FeMoO4 provides a distinct structural framework that offers different surface active sites, positioning it as a specialized alternative to the more common transition metal oxides like NiO in oxygen-evolution research.
