Green Synthesis of α-Fe2O (hematite) Nanoparticles using Tragacanth Gel
نویسندگان
چکیده مقاله:
α-Fe2O3 (hematite) nanoparticles were synthesized using tragacanth gel as biotemplate andiron chloride as the iron source by the sol-gel method. This method has many advantages suchas nontoxic, economic viability, ease to scale up, less time consuming and environmentalfriendly approach for the synthesis of α-Fe2O3 nanoparticles without using any organicchemicals. Nanoparticles were characterized by Fourier transform infrared (FT-IR)spectroscopy, UV-visible spectroscopy and X-ray diffraction (XRD). The powder X-raydiffraction (XRD) analysis revealed the formation of Rhombohedral phase α-Fe2O3 withaverage particle size of 21 nm.
