VCrO4
VCrO4 is a semiconducting complex oxide catalyst with a structure that supports advanced chemical reactivity.
About VCrO4
VCrO4 is a complex oxide belonging to the spinel-related family of materials. Characterized by its semiconducting electronic nature, this compound represents a sophisticated arrangement of vanadium and chromium cations within an oxygen framework, offering unique pathways for charge transfer and surface reactivity. Its thermodynamic profile suggests it is near the stability hull, indicating that it is a viable target for experimental synthesis and structural characterization. As a member of the broader class of spinel oxide catalysts, VCrO4 is investigated for its potential to facilitate chemical transformations where precise electronic control is required. Its structural versatility, supported by numerous reported configurations, allows it to function in environments where traditional binary oxides might lack the necessary catalytic activity or selectivity.
Key Properties
Cross-validated computational properties for VCrO4, 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.

How It Compares
Within the spinel oxide catalysts class.
Within the diverse landscape of spinel and related oxide catalysts, VCrO4 occupies a specialized niche compared to simpler binary oxides like ZnO or NiO. While materials such as MgAl2O4 serve as robust structural supports, VCrO4 leverages the redox-active nature of its transition metal components to offer distinct catalytic advantages, positioning it closer in functional complexity to perovskite-structured systems like LaMnO3 rather than the more inert insulating oxides.
