VFeO4
VFeO4 is a semiconducting transition metal oxide being explored as a catalyst for oxygen-evolution reactions in electrochemical energy systems.
About VFeO4
VFeO4 is a semiconducting oxide that functions within the class of oxygen-evolution catalysts. Its structural characteristics and electronic properties make it a subject of interest for researchers seeking efficient materials for electrochemical water splitting and related energy applications. Being situated near the thermodynamic hull, it is considered a viable candidate for experimental synthesis and further characterization. The material demonstrates a notable degree of structural diversity, supported by multiple reported configurations across existing materials databases. This suggests a flexible framework that may be tuned for specific catalytic performance, positioning it as a potentially valuable addition to the catalog of transition metal oxides used in energy conversion technologies.
Key Properties
Cross-validated computational properties for VFeO4, 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.
Unlike well-established battery cathode materials such as LiCoO2 or LiMn2O4, which are optimized for ion intercalation, VFeO4 is primarily investigated for its role in oxygen-evolution catalysis. While it shares the transition metal oxide framework common to complex perovskites like LaMnO3 or BiFeO3, its specific stoichiometry and semiconducting nature provide a distinct electronic environment that differentiates its catalytic activity from the more widely studied nickel-based oxides like NiO or La2NiO4.
