Long α-Fe2O3hollow fibers have been prepared through a facile sol–gel combined co-electrospinning technique using ferric citrate as precursor, and α-Fe and γ-Fe2O3hollow fibers have been obtained by reduction and reoxidation at different conditions. The outer diameter of the as-prepared hollow fibers is 0.5–5 μm with wall thickness of 200–800 nm. The obtained tubular fibers were characterized by thermal gravimetric (TG), FT-IR spectra, X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and Raman techniques. In addition, magnetic properties of α-Fe and γ-Fe2O3hollow fibers have also been investigated.
