This versatility makes it an intriguing candidate for researchers looking to tune catalytic performance through structural modifications in advanced energy systems.
Key Properties
Cross-validated computational properties for TaFeO4, 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 the lithium-based intercalation oxides such as LiCoO2 or LiNiO2 which are primarily utilized for battery cathodes, TaFeO4 functions as a stable semiconducting catalyst. It shares the complex oxide architecture found in perovskite-related materials like LaMnO3 or BiFeO3, yet it offers a distinct chemical environment centered on tantalum and iron that differentiates its catalytic pathway from the nickel-rich members of the class.
