Product Application of Triiron Tetraoxide CAS#1317-61-9
Iron(II,III) oxide (Fe₃O₄) can serve as a heterogeneous catalyst in Fenton-like oxidation processes for rhodamine B. It is also applicable as an anode material in the manufacture of lithium-ion batteries. In addition, Fe₃O₄ can be employed as a catalyst for the oxygen reduction reaction (ORR) in anion exchange membrane fuel cells.
