چکیده

α-Fe2O3 (hematite) nanoparticles were synthesized using tragacanth gel as biotemplate and
iron chloride as the iron source by the sol-gel method. This method has many advantages such
as nontoxic, economic viability, ease to scale up, less time consuming and environmental
friendly approach for the synthesis of α-Fe2O3 nanoparticles without using any organic
chemicals. Nanoparticles were characterized by Fourier transform infrared (FT-IR)
spectroscopy, UV-visible spectroscopy and X-ray diffraction (XRD). The powder X-ray
diffraction (XRD) analysis revealed the formation of Rhombohedral phase α-Fe2O3 with
average particle size of 21 nm.
