General description

Iron is present in the form of iron(III) oxide in almost all natural sources of water. It is widely used as a supplement of iron and in solar photoelectrolysis cells. It is a highly stable n-type semiconductor, and possesses a band gap of 2.0 to 2.2eV. It is widely used in solar photoelectrolysis cells. Self-organized nanoporous iron(III) oxide (haematite) has been prepared.

Application

Iron(III) oxide may be used in the preparation of iron(III) oxide-hydrate gels.
