Cu2O4Rb2
Cu2O4Rb2 is a stable, semiconducting ternary oxide catalyst used in materials research.
About Cu2O4Rb2
Cu2O4Rb2 is a semiconducting oxide that sits firmly on the thermodynamic convex hull, indicating high stability in its crystalline form. As a member of the spinel oxide catalyst family, it offers a unique electronic environment suitable for surface-mediated chemical transformations.
This material is of significant interest to researchers investigating complex ternary oxides for catalytic applications. Its structural integrity and semiconducting nature make it a robust candidate for processes requiring stable, active metal-oxide surfaces.
Key Properties
Cross-validated computational properties for Cu2O4Rb2, 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.
Within the diverse group of spinel and transition metal oxide catalysts, Cu2O4Rb2 distinguishes itself through its specific ternary composition compared to binary counterparts like CuO or ZnO. While simple oxides like CuO are widely utilized for their redox properties, the inclusion of rubidium in this spinel structure provides a different electronic landscape than that found in more common aluminate spinels such as MgAl2O4.
