About TlCoO3
TlCoO3 is a semiconducting oxide that functions within the class of oxygen-evolution catalysts. Its metastable nature makes it a subject of significant interest for researchers investigating phase stability and catalytic performance in electrochemical systems.
This compound represents a unique entry in the study of transition metal oxides. By leveraging its electronic characteristics, scientists aim to understand how thallium-based cobaltites contribute to the efficiency of water-splitting reactions and other related catalytic processes.
Key Properties
Cross-validated computational properties for TlCoO3, 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.
