CrNO2
CrNO2 is a semiconducting transition metal nitroxide that belongs to the broader class of spinel oxide catalysts.
About CrNO2
CrNO2 is a semiconducting material categorized within the spinel oxide catalyst family. Its electronic structure suggests potential utility in specialized catalytic processes where moderate charge transport is required for surface reactions. Due to its position above the thermodynamic hull, it is considered a metastable phase. This metastability makes it a subject of interest for researchers investigating synthetic pathways to stabilize complex transition metal nitroxides.
Key Properties
Cross-validated computational properties for CrNO2, aggregated across 4 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 binary oxides such as NiO, ZnO, and Al2O3, CrNO2 represents a more complex and less stable member of the oxide catalyst landscape. While perovskite-structured compounds like LaMnO3 and LaNiO3 are frequently employed for their robust catalytic activity, CrNO2 offers a distinct structural profile that requires careful synthesis to maintain its specific semiconducting characteristics.
