Co5Te3O16
Co5Te3O16 is a semiconducting cobalt tellurium oxide investigated for its potential role in catalytic oxygen evolution reactions.
About Co5Te3O16
Co5Te3O16 is a complex semiconducting oxide featuring a unique arrangement of cobalt and tellurium atoms. Its electronic properties make it an interesting subject for researchers investigating advanced materials for electrochemical energy conversion processes.
While it is classified among oxide oxygen-evolution catalysts, its thermodynamic state indicates it sits above the stability hull. This suggests that while the material is synthetically accessible, it may represent a metastable phase that requires specific conditions for formation and characterization.
Key Properties
Cross-validated computational properties for Co5Te3O16, 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.
