Abstract

Fe2O3 nanorods have been successfully synthesized by a hydrothermal method using stainless steel Teflon autoclave. The solution of FeCl3 and Urea was transferred to Teflon-lined stainless-steel autoclave and then maintained the temperature 180oC for 24 hrs. As prepared Fe2O3 powder were characterized by X-ray Diffraction (XRD) and the result shows the formation of Hematite phase of Fe2O3 after calcination at 400oC of 2h. Field Emission Scanning Electron Microscopy (FESEM) was used to study the morphology of synthesized Fe2O3 powder and the result indicates that bunch of nanorods were formed with width 44 nm and length of 220 nm.  Also, Fourier Transform Infrared spectroscopy (FTIR) and X-ray Photoelectron Spectroscopy (XPS) techniques were used to characterize synthesized Fe2O3 nanorods. To study the humidity sensing performance of Fe2O3 nanorods, sensor was synthesized as interdigitated electrode coated with sensing material on top of the electrode. The present study investigated good humidity sensing performance of Fe2O3 nanorods at room temperature in humidity (RH) range of 11%-97% at DC condition.
