CoNiO2
CoNiO2 is a stable, semiconducting oxide material utilized primarily as a catalyst for oxygen-evolution reactions in electrochemical systems.
About CoNiO2
CoNiO2 is a semiconducting oxide that sits on the convex hull, indicating high thermodynamic stability. This stability makes it a compelling candidate for electrochemical applications, particularly where structural integrity is required during prolonged operation. Its electronic character facilitates charge transfer, which is essential for its role in catalytic processes.
As a member of the oxide oxygen-evolution catalyst class, this material is studied for its ability to mediate the water-splitting reaction. By leveraging the synergistic effects of cobalt and nickel, it provides an alternative pathway for efficient oxygen production, contributing to the development of sustainable energy conversion technologies.
Key Properties
Cross-validated computational properties for CoNiO2, 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 oxide oxygen-evolution catalysts class.
Within the broader family of transition metal oxides, CoNiO2 offers a distinct compositional balance compared to binary oxides like NiO or complex layered structures like LiCoO2. While many members of this class, such as LaNiO3 or LaMnO3, are primarily investigated for their magnetic or electronic transport properties, CoNiO2 is specifically optimized for its catalytic activity, bridging the gap between simple binary systems and more complex multi-component perovskites.
