Synthesis and Applications of Iron oxides


Iron oxides are some of technological applications' most important transition metal oxides. Sixteen pure phases of iron oxides, i.e., oxides, hydroxides, and oxy-hydroxides, are known to date. These compounds mostly contain iron in the trivalent state and have low solubility and brilliant colors (Cornell & Schwertmann, 1996). The oxides find applications as catalysts, sorbents, pigments, flocculants, coatings, gas sensors, ion exchangers, and lubricants (Miyata et al., 1978; Sharrock & Bodnar, 1985; Vissokov & Pirgov, 1996; Choo & Kang, 2003). Iron oxide nanocomposites have potential applications in areas such as magnetic recording, magnetic data storage devices, and toners and inks for xerography, as well as in MRI, wastewater treatment, bioseparation, and medicine (Raj & Moskovitz, 1990; Häfeli et al., 1997; Schutt et al., 1997; Denizli & Say, 2001). Magnetic nanoparticles are widely studied because they offer great possibilities in several diagnostic applications and therapies (Laurent et al., 2009; Veiseh et al., 2009). The use of SPION-based MRI contrast agents is well-established, and several SPIONs have been approved by the U.S. Food and Drug Administration (FDA) (Hamm et al., 1994; Reimer & Balzer, 2003). For biomedical applications, it is crucial that SPIONs have a well-defined shape, are monodispersed, and exhibit a high magnetization capacity (Laurent et al., 2009; Kunzmann et al., 2011b).
