CeFeO3

Cerium iron oxide (CeFeO3) is a mixed-valence ceramic compound belonging to the perovskite family of semiconductors, combining rare-earth and transition-metal elements. This material is primarily investigated in research contexts for photocatalytic and electrochemical applications, where its ability to facilitate electron transfer and oxygen vacancy generation makes it attractive for environmental remediation and energy conversion. Engineers consider CeFeO3 over conventional semiconductors like TiO2 when enhanced catalytic activity under visible light or improved charge carrier mobility is critical, though it remains largely in the development phase rather than established industrial production.
