摘要
A facile method to prepare alpha-Fe2O3 micro/nanoparticles by using the nanorod complex of FeCl3 and methyl orange as precursors has been demonstrated. The single-crystalline alpha-Fe2O3 micro/nanoparticles are successfully obtained by pyrolysis of the precursors at 800 degrees C for 4 h. The growth process of the precursor is investigated. The products are characterized by x-ray powder diffraction (XRD), thermogravimetry analysis (TGA), magnetization measurement, scanning electron microscopy (SEM) and transmission electron microscopy (TEM) and high-resolution TEM. The potential applications in water treatment and gas-sensing properties are investigated.
