Monodisperse hematite porous nanospheres: synthesis, characterization, and applications for gas sensors

Journal Article


Abstract


  • Monodisperse alpha-Fe2O3 porous nanospheres with uniform shape and size have been synthesized via a facile template-free route. X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), and Raman spectroscopy were employed to characterize the product, showing the high quality of the as-prepared alpha-Fe2O3 porous nanospheres. Furthermore, the alpha-Fe2O3 porous nanospheres can selectively detect ethanol, formaldehyde and acetic acid, with a rapid response and high sensitivity, from a series of flammable and toxic/corrosive gases, indicating their potential applications for high sensitivity gas sensors.
