Li2FeO2
Li2FeO2 is a stable, wide-gap insulating lithium iron oxide being investigated for its potential role in oxygen-evolution catalysis.
About Li2FeO2
Li2FeO2 is an insulating oxide belonging to the class of oxygen-evolution catalysts. Its electronic structure is characterized by a wide band gap, distinguishing it from more metallic transition metal oxides within the same functional category. The material exhibits thermodynamic stability near the convex hull, suggesting it is a viable candidate for experimental synthesis and further electrochemical characterization. Its structural diversity is highlighted by numerous reported configurations across multiple materials databases, underscoring its significance in solid-state chemistry research. As a lithium-containing iron oxide, it serves as a platform for investigating redox-active oxygen mechanisms in catalytic environments.
Key Properties
Cross-validated computational properties for Li2FeO2, 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 family of oxygen-evolution catalysts, Li2FeO2 occupies a unique niche compared to more conductive or highly studied materials like LiCoO2 or LiNiO2. While many members of this class, such as LaNiO3 or LaMnO3, are characterized by their metallic or semi-metallic behavior, Li2FeO2 remains a wide-gap insulator. This electronic distinction positions it as an intriguing alternative to the more conventional spinel or layered oxides like LiMn2O4, potentially offering different pathways for charge transfer and catalytic activity in electrochemical systems.
