About Co3TeO8
Co3TeO8 is a semiconducting oxide that functions as a specialized catalyst for the oxygen-evolution reaction. Its unique structural arrangement allows it to participate in complex electrochemical processes, making it a subject of interest for researchers seeking to optimize catalytic efficiency in energy storage and conversion systems.
As a metastable phase, this material offers distinct reactivity profiles compared to more conventional, highly stable oxides. Its electronic character is defined by its semiconducting nature, which facilitates the charge transfer necessary for effective catalytic performance in various electrochemical environments.
Key Properties
Cross-validated computational properties for Co3TeO8, 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 broader class of oxide oxygen-evolution catalysts, Co3TeO8 occupies a niche position compared to more widely utilized transition metal oxides like NiO or LiCoO2. While materials such as LiCoO2 are staples in commercial battery technology, Co3TeO8 is distinguished by its metastable nature and specific tellurium-based stoichiometry, which provides a different structural framework for exploring catalytic activity than the simpler binary or perovskite-structured oxides like LaNiO3.
