CaCo2O5
CaCo2O5 is a metastable, semiconducting cobalt oxide used primarily in the study and development of oxygen-evolution catalysts.
About CaCo2O5
CaCo2O5 is a semiconducting oxide that functions as a catalyst for the oxygen-evolution reaction. Its metastable nature makes it a subject of significant interest for researchers aiming to tune catalytic activity through structural modifications in transition metal oxides. The material's electronic properties are central to its performance in electrochemical environments, where it facilitates complex charge transfer processes. As a cobalt-based oxide, it plays a vital role in the ongoing search for efficient, earth-abundant catalysts for water splitting and energy storage applications.
Key Properties
Cross-validated computational properties for CaCo2O5, 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 family of oxygen-evolution catalysts, CaCo2O5 occupies a niche position compared to more widely utilized materials like LiCoO2 or LiMn2O4. While compounds such as LiCoO2 are staples in commercial battery technology, CaCo2O5 is distinguished by its metastable phase, which offers unique catalytic pathways that differ from the more thermodynamically stable perovskite-like structures found in LaMnO3 or LaNiO3.
