Abstract

We report the facile synthesis of ultrathin β-FeOOH and ε-Fe₂O₃ nanowires with diameter of 2-3 nm. The β-FeOOH nanowires show the unique optical properties attributed to the size- and shape-related quantum confinement effect. Upon heat treatment, they are transformed into ε-Fe₂O₃ nanowires, which exhibit the different magnetic properties compared with the previously reported ε-Fe₂O₃ nanostructures synthesized in silica matrices. The ε-Fe₂O₃ nanowires also exhibit high catalytic efficiency and hold potential for environmental-remediation applications.
