General description

Iron nickel oxide (Fe2O3/NiO) nanopowder is a class of nanomaterial with properties such as superior magnetic, electrical and selective absorption. It can be used as an additive in the formation of membranes for water treatment. [1]

Application

Fe2O3/NiO can be used for applications such as:
  • fabrication of magnetic nanofiber for data storage and transfer[2]
  • electrocatalysts for the splitting of alkaline water[3]
  • formation of composite nanofibers for efficient water oxidation electrocatalysis[4]
