General description
Iron(II,III) oxide is an earth-abundant magneticoxide that has a high specific surface area, and good dispersion. The presenceof Fe3+ and Fe2+ with equal numbers in the Fe3O4structure provides higher light absorption and as a result superiorelectrocatalytic activities and high performance in solar cells compared toother iron oxides.
Application
Iron(II,III) oxide can be used as:
- A starting material to synthesize Ca2Fe2O5 (srebrodolskite) microspheres via a single-stage flame spheroidisation (FS) process.
- A catalyst for reverse water gas shift reactions(RWGS).
