Synthesis of novel Sb2O3 and Sb2O5 nanorods

Sb2O3 and Sb2O5 nanorods have been prepared by using a microemulsion method for the system of AOT–water–toluene. X-ray diffraction and high resolution electron microscopy (HREM) were used to characterize the phase and size as well as shape of the Sb2O3 and Sb2O5 nanorods. These nanorods have a diameter of 10–50 nm and a length of up to 25 μm. A possible mechanism for the formation of the nanorods is discussed.
