Cr3InO8
Cr3InO8 is a semiconducting ternary oxide catalyst characterized by its complex structural arrangements and metastable nature.

About Cr3InO8
Cr3InO8 is a semiconducting oxide compound that belongs to the complex family of spinel-related materials. Its electronic structure and composition make it a subject of interest for researchers investigating specialized catalytic pathways and advanced material synthesis.
While it is currently identified as being above the thermodynamic hull, the existence of multiple reported structures highlights its significance in fundamental materials science. It serves as a model for understanding how indium and chromium interactions influence the stability and potential reactivity of oxide frameworks.
Key Properties
Cross-validated computational properties for Cr3InO8, 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 highly stable and widely utilized industrial catalysts such as ZnO or MgAl2O4, Cr3InO8 occupies a more precarious position in the thermodynamic landscape. While common spinel oxides like MgAl2O4 are celebrated for their structural robustness, Cr3InO8 represents a more exotic, metastable variant that offers a distinct electronic profile compared to the simple binary oxides like CuO or NiO.
