Preparation of monodispersed α-Fe2O3 nanoparticles by a hydrothermal synthetic route

Preparation of monodispersed α-Fe2O3 nanoparticles by a hydrothermal synthetic route Monodispersed α-Fe2O3 nanoparticles modified by sodium dodecylbenzene sulfonate (SDBS) surfactant and assisted by glycerol have been successfully synthesized via a hydrothermal process using FeCl3·6H2O as the starting precursor. These nanoparticles possess good crystallinity and have an average particle size of 100 nm. The as-prepared products are characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, and a superconducting quantum interference device magnetometer. SDBS and glycerol played an important role in controlling the final morphology of the products. Magnetic hysteresis measurements reveal that monodispersed α-Fe2O3 nanoparticles exhibit normal ferromagnetic behaviors with the remanent magnetization and coercivity of 0.2389 emu/g and 2339.0 Oe at room temperature. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Research on Chemical Intermediates Springer Journals
