TlNiO3
TlNiO3 is a metastable, semimetallic nickel-based oxide investigated for its catalytic properties in oxygen-evolution processes.
About TlNiO3
TlNiO3 is a complex oxide belonging to the oxygen-evolution catalyst class, characterized by a near-zero-gap electronic structure that suggests semimetallic behavior. Its metastable nature makes it a subject of significant interest for researchers investigating phase stability and catalytic activity in electrochemical systems.
As a member of the nickel-based oxide family, this compound is studied for its potential in energy conversion technologies. The unique interplay between the thallium and nickel cations provides a distinct electronic environment that differentiates it from more traditional insulating or semiconducting oxides.
Key Properties
Cross-validated computational properties for TlNiO3, 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.
Within the diverse group of oxygen-evolution catalysts, TlNiO3 occupies a niche position compared to stable perovskites like LaNiO3 or LaMnO3. While many members of this class, such as NiO or LiCoO2, are well-established for their robustness and industrial utility, TlNiO3 represents a more specialized, metastable phase that challenges standard structural paradigms found in more common battery materials like LiNiO2.
