Description

General description

Iron(II,III) oxide nanopowder is a fine powder composed of iron oxide particles with a size ranging from 50-100 nm. It is also known as ferrous ferric oxide or ferrosoferric oxide. Iron(II,III) oxide is a reddish-brown, magnetic material that is stable and chemically inert. It is commonly used as a pigment in paints, coatings, and ceramics, and it is also used as a catalyst in many chemical reactions. As a nanopowder form, this iron(II,III) oxide has a large surface area, which makes it more effective as a catalyst.

Application

Iron(II,III) oxide (Fe₃O₄) can be used as a heterogeneous catalyst for the Fenton type oxidation of rhodamine B. It can be used as an anode material for the fabrication of lithium-ion batteries. Fe₃O₄ can also be utilized in the catalysis of the oxygen reduction reaction (ORR) in the anion exchange membrane fuel cell.
