Cu11O26V6
Cu11O26V6 is a metastable, semiconducting copper-vanadium oxide used in advanced catalytic research.
About Cu11O26V6
Cu11O26V6 is a complex copper-vanadium oxide that functions as a semiconducting material within the broader family of spinel-related catalysts. Its unique stoichiometry and metastable nature make it a subject of interest for researchers investigating non-equilibrium phase synthesis and specialized catalytic pathways.
Because it exists in a metastable state, this compound offers distinct reactivity profiles compared to more common, highly stable oxides. Its electronic character suggests potential utility in oxidation-reduction processes where tunable semiconducting behavior is required to facilitate surface reactions.
Key Properties
Cross-validated computational properties for Cu11O26V6, aggregated across 3 databases.

How It Compares
Within the spinel oxide catalysts class.
Unlike the highly stable and widely utilized binary oxides such as CuO or ZnO, Cu11O26V6 represents a more intricate and less common structural arrangement. While materials like MgAl2O4 serve as standard structural benchmarks for the spinel class, this compound is distinguished by its complex metal-to-oxygen ratio and its role as a specialized, metastable alternative to the more conventional perovskite-type catalysts like LaMnO3.
