NiCO
NiCO is a metastable, insulating nickel-based oxide investigated for its potential role in oxygen-evolution catalytic processes.
About NiCO
NiCO is an inorganic compound categorized within the class of oxide oxygen-evolution catalysts. As a wide-band-gap insulator, it exhibits distinct electronic properties that differentiate it from the metallic or semi-conducting oxides often utilized in electrochemical energy conversion.
Due to its position above the thermodynamic hull, this material is considered metastable, posing significant challenges for synthesis and long-term stability. Its study contributes to the broader understanding of nickel-based oxide systems and their potential roles in complex catalytic environments.
Key Properties
Cross-validated computational properties for NiCO, 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 oxide oxygen-evolution catalysts class.
Unlike the highly stable and widely utilized NiO or the layered lithium-intercalation oxides like LiCoO2 and LiNiO2, NiCO represents a more exotic and less thermodynamically favored phase within the nickel-oxide family, requiring specialized conditions to maintain its structural integrity compared to the robust perovskite structures like LaNiO3 or LaMnO3.
