Paper Title:
Hydrothermal Synthesis and Gas Sensing Properties of α-Fe2O3 Hollow Microspheres and Nanorods
  Abstract

α-Fe2O3 hollow microspheres and nanorods were synthesized via a hydrothermal method using glucose and ethylenediaminetetraacetic acid (EDTA) as morphology controlled agents, followed by calcination at 500 °C for 4 h in air. The crystal structures of products were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the hollow microspheres with diameters of 1-2 μm are consist of nanoparticles (80-100 nm), and the nanorods have a structure in the diameter of 80-100 nm and length about 1 μm. Furthermore, the α-Fe2O3 hollow microspheres show higher gas response to ethanol than that of nanorods and nanoparticles.
