SmFeO3 is a stable, semiconducting perovskite oxide utilized for its catalytic properties in oxygen-evolution reactions.
About Samarium orthoferrite
SmFeO3 is a semiconducting oxide that sits firmly on the thermodynamic convex hull, indicating high stability. As a member of the orthoferrite family, it features a perovskite-type structure that is highly valued for its robust chemical nature and potential in electrochemical processes.
This material is primarily investigated for its role in oxygen-evolution catalysis. Its electronic configuration and stable crystal lattice make it a compelling candidate for researchers seeking durable, efficient alternatives to traditional noble metal catalysts in energy conversion systems.
Key Properties
Cross-validated computational properties for Samarium orthoferrite, aggregated across 2 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.
