V2ZnO5
V2ZnO5 is a metastable, semiconducting spinel oxide used primarily in research for its potential catalytic properties.
About V2ZnO5
V2ZnO5 is a semiconducting oxide that belongs to the broader family of spinel-structured materials. Its electronic character and metastable nature make it an intriguing subject for researchers investigating complex transition metal oxides for catalytic performance.
Because it exists in a metastable state, this compound offers unique pathways for chemical reactivity compared to more stable, conventional oxides. Its structural versatility is supported by multiple reported configurations, positioning it as a specialized candidate for targeted surface-mediated reactions.
Key Properties
Cross-validated computational properties for V2ZnO5, 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 highly stable and widely utilized MgAl2O4 or simple binary oxides like ZnO and NiO, V2ZnO5 occupies a more delicate thermodynamic niche. While perovskite-structured members like LaMnO3 are often studied for their robust magnetic and electronic properties, V2ZnO5 is distinguished by its specific spinel-related architecture and semiconducting behavior, which provides a different active site environment for catalysis.
