Ca2CuO3
Ca2CuO3 is a metallic, near-stable oxide catalyst used in advanced chemical synthesis research.

About Ca2CuO3
Ca2CuO3 is a metallic oxide that sits near the thermodynamic hull, indicating high potential for experimental synthesis and practical utility. As a member of the broader oxide catalyst family, its electronic character allows for unique charge transfer properties essential for surface-mediated reactions.
This compound is primarily investigated for its catalytic potential in industrial chemical processes. Its structural arrangement and metallic nature make it a compelling candidate for researchers seeking to optimize reactivity in complex oxidation cycles.
Key Properties
Cross-validated computational properties for Ca2CuO3, 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 spinel oxide catalysts class.
Unlike the insulating binary oxides in its class such as ZnO or Al2O3, Ca2CuO3 exhibits metallic behavior, placing it in a distinct electronic category from the traditional spinel structures like MgAl2O4. While it shares the oxide framework common to LaMnO3 and LaNiO3, its specific stoichiometry offers a different structural landscape for catalytic active sites compared to these more complex perovskite-related materials.
