FeSO5
FeSO5 is a semiconducting iron-based oxide being studied for its potential role as a catalyst in oxygen-evolution reactions.
About FeSO5
FeSO5 is a semiconducting oxide that belongs to the class of oxygen-evolution catalysts. Its electronic structure and composition make it a subject of interest for researchers looking to optimize electrochemical water splitting processes. Despite its potential utility, the compound is characterized as being above the thermodynamic hull, suggesting it is a metastable phase that requires specific synthesis conditions to stabilize. The existence of multiple reported structures highlights its complex potential for structural tuning in catalytic applications. This material represents a unique intersection of iron-based chemistry and oxygen-evolution research, where its semiconducting nature plays a critical role in charge transfer mechanisms. While its stability presents a challenge, the variety of structural configurations identified in databases provides a foundation for further investigation into its catalytic performance.
Key Properties
Cross-validated computational properties for FeSO5, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the diverse landscape of oxygen-evolution catalysts, FeSO5 occupies a distinct position compared to more stable, widely utilized materials like LiCoO2 or LaMnO3. While compounds such as NiO and La2NiO4 are well-established, robust catalysts, FeSO5 is distinguished by its metastable status, which contrasts with the thermodynamic stability typically associated with the more common perovskite or rock-salt members of this class.
