Its structural arrangement is well-documented, with multiple reported configurations across major materials databases.
The material is primarily studied for its potential in energy conversion and storage technologies. By participating in oxygen-evolution reactions, this cobalt-based oxide serves as a functional component in the development of efficient electrolyzers and sustainable energy systems.
Key Properties
Cross-validated computational properties for CoSe2O5, 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.
Unlike the widely utilized layered oxides such as LiCoO2 or LiNiO2, which are primarily optimized for lithium-ion battery cathodes, CoSe2O5 is specifically categorized within the realm of oxygen-evolution catalysts. While perovskite-structured materials like LaMnO3 and LaNiO3 are frequently investigated for their high catalytic activity, CoSe2O5 offers a distinct structural motif that contributes to the diversity of available oxide catalysts for electrochemical applications.
