Fe-bearing layered double hydroxides (Fe-LDH) have not been much used commercially compared with hydrotalcite-like compounds. However, elemental Fe has the least effect on the environment, and Fe ore is in abundant supply as a major resource. Also, Fe-bearing compounds tend to be more stable, and they potentially show a catalytic activity and a redox reaction. Therefore, it is expected that Fe-LDH are very beneficial for an environment-friendly society. This paper reviews the syntheses, properties and applications of Fe-LDH (Fe^<II>-Fe^<III> LDH, Mg-Fe^<III> LDH, Zn-Fe^<III> LDH and Fe^<II>-Al LDH) in order to promote the utilization of them as green materials. After an introduction describing the main features of these compounds, emphasis is put on the synthesis methods, characterization and applications.
