TaMnO4
TaMnO4 is a semiconducting transition metal oxide being researched for its potential as a catalyst in oxygen-evolution reactions.
About TaMnO4
TaMnO4 is a complex oxide belonging to the class of oxygen-evolution catalysts. Its semiconducting electronic nature makes it an intriguing candidate for photoelectrochemical water splitting and related catalytic processes where charge transport is critical. The material is characterized by its proximity to the thermodynamic stability hull, suggesting that it is a viable target for experimental synthesis and structural characterization. With multiple reported structures across major databases, it represents a significant, albeit specialized, entry in the study of transition metal oxides. Its role in the oxygen-evolution reaction is defined by the interplay between the tantalum and manganese centers, which influence its surface reactivity and catalytic efficiency. Researchers focus on such oxides to develop more sustainable and cost-effective alternatives to noble metal catalysts.
Key Properties
Cross-validated computational properties for TaMnO4, 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.

How It Compares
Within the oxide oxygen-evolution catalysts class.
Within the broad category of oxide oxygen-evolution catalysts, TaMnO4 occupies a distinct niche compared to well-established materials like LaMnO3 or LiMn2O4. While many of its class members, such as the layered lithium-based oxides or the perovskite-structured lanthanum compounds, are extensively utilized in battery technologies or high-temperature catalysis, TaMnO4 is primarily investigated for its specific catalytic potential in electrochemical water oxidation. Unlike the highly stable and widely commercialized NiO, TaMnO4 remains a subject of fundamental materials design, offering a unique electronic environment that differentiates it from the more conventional perovskite or spinel structures found in its class.
