TiFe2O5 is a semiconducting, metastable iron-titanium oxide utilized primarily in the study and development of oxygen-evolution catalysts.
About pseudobrookite
TiFe2O5 is a semiconducting oxide that functions as a metastable phase within the broader family of oxygen-evolution catalysts. Its unique structural arrangement allows it to participate in electrochemical processes, making it a subject of interest for researchers seeking to optimize catalytic efficiency in energy conversion systems.
Because it exists in a metastable state, this compound offers distinct pathways for reactivity compared to more thermodynamically stable oxides. Its electronic character is well-suited for applications where charge transfer at the electrode-electrolyte interface is critical for driving oxygen evolution reactions.
Key Properties
Cross-validated computational properties for pseudobrookite, 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.
While many members of the oxide catalyst class, such as NiO or the layered LiCoO2, are widely utilized for their high stability and well-defined electrochemical performance, TiFe2O5 stands out due to its metastable nature. Unlike the perovskite-structured LaMnO3 or BiFeO3, which are often studied for their complex magnetic and catalytic interplay, TiFe2O5 provides a different structural framework that challenges conventional stability-activity trade-offs in catalytic design.
