Fe2GeO4 is a thermodynamically stable semiconducting oxide used in research for oxygen-evolution catalysis.
About Fe2GeO4
Fe2GeO4 is a semiconducting oxide that sits firmly on the thermodynamic convex hull, indicating high structural stability. As a member of the oxide oxygen-evolution catalyst family, it serves as a critical candidate for electrochemical energy conversion processes where stable, efficient materials are required to drive oxygen production.
Its electronic character makes it an intriguing subject for research into charge transfer mechanisms during catalysis. By balancing iron and germanium cations within an oxygen framework, this compound provides a robust platform for investigating the fundamental surface interactions necessary for sustainable water splitting technologies.
Key Properties
Cross-validated computational properties for Fe2GeO4, 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.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.
