Abstract
Densely packed single-crystal Bi 2Fe 4O 9 nanowires were successfully synthesized by a template-induced citrate-based sol–gel process. The structural properties of the nanowires were characterized using many techniques. The results of scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed that Bi 2Fe 4O 9 nanowires possessed a uniform length and diameter, which were controlled by the thickness and the pore diameter of the applied porous anodic aluminum oxide (AAO) template, respectively. The results of X-ray diffraction (XRD) and the selected area electron diffraction (SAED) indicated that Bi 2Fe 4O 9 nanowires had an orthorhombic single-crystal structure. Furthermore, the energy-dispersive X-ray (EDX) spectroscopy demonstrated that the stoichiometric Bi 2Fe 4O 9 was formed. The possible formation mechanism of nanowires was also discussed.
