CoP2O7
Cobalt pyrophosphate
CoP2O7 is a semiconducting cobalt-based pyrophosphate oxide primarily investigated for its potential as a catalyst in oxygen-evolution reactions.
About Cobalt pyrophosphate
Cobalt pyrophosphate is a semiconducting oxide that serves as a specialized oxygen-evolution catalyst. Its unique structural arrangement makes it a subject of interest for researchers studying efficient water-splitting reactions and electrochemical energy conversion systems. As a metastable phase, this compound offers distinct reactivity profiles compared to more common stable oxides. Its electronic properties are highly tuned for catalytic applications where charge transfer at the electrode interface is critical for performance.
Key Properties
Cross-validated computational properties for Cobalt pyrophosphate, 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 diverse landscape of oxygen-evolution catalysts, CoP2O7 occupies a niche position distinct from the well-characterized transition metal oxides like LiCoO2 or NiO. While many class members such as LaNiO3 or LaMnO3 rely on complex perovskite architectures, this pyrophosphate utilizes a phosphate-based framework that provides a different chemical environment for catalytic activity, offering an alternative pathway for oxygen evolution compared to the standard spinel or layered structures found in LiMn2O4.
