Iron Oxide (Fe<sub>3</sub>O<sub>4</sub>) Nanopowder CAS 1317-61-9

Iron Oxide Nanopowder Containing Iron (II) and Iron (III) Ions

Used in a wide range of applications including magnetic sealing, magnetic healthcare, catalysts, pigments, batteries, supercapacitors, nanomedicine and hydrogen evolution

Overview | Product Information | Related Products | Technical Support

Iron oxide (Fe₃O₄), CAS number 1317-61-9, contains both iron (II) and iron (III) ions, also written as FeO·Fe₂O₃. It occurs in nature as the mineral magnetite, exhibiting ferrimagnetism.

Fe₃O₄ powder has been used as pigments, catalysts, and contrast agents in MRI scanning. More recently, iron oxide nanopowder is used as anode materials with carbon-based materials. These composite anode materials demonstrate a specific capacity of 980 mAh/g at a fast-charging rate of 4C with outstanding cycling stability.

Also used as a catalyst in hydrogen evolution reaction (HER), this Cu-FeOOH/Fe₃O₄ exhibits excellent stability and a low overpotential of 285 mV at 500 mA/cm² for alkaline HER. Density functional theory (DFT) calculations show that the catalyst decreases the energy barrier of water dissociation and hydrogen generation, enabling efficient HER.
