Synthesis of spherical and Rod-Like EDTA assisted α-Fe2O3 nanoparticles via Co-precipitation method

Abstract

Abstract Spherical and Rod-Like α-Fe2O3 nanoparticles were effectively integrated via simple chemical co-precipitation strategy modified by Ethylenediaminetetraacetic acid (EDTA) as a surfactant. X-ray diffraction (XRD) study determined the phase identification, crystalline size and structure recognizance of as synthesized material. The crystalline size has been calculated by Debye Scherrer’s formula and the crystalline size was 20.68 nm. The optical properties of material determined with the assistance of Ultra violet and visible spectroscopy (UV–Vis spectroscopy). The excitation wavelength of synthesized material was 566 nm and the band gap was 1.97 eV. The morphology of the readied nanoparticles were concentrated by utilizing field emission electron microscopy (FE-SEM) uncovered spherical and rod like structure of nanoparticle. Energy Dispersive X-ray Spectrum (EDX spectrum) results presence of Iron and Oxygen elements only. The high-resolution transmission electron microscopy (HR-TEM) of the prepared sample shows the morphology and particle size of nanoparticles. The morphology of prepared sample manifested spherical and rod-like shape particle size analyzed from HR-TEM and XRD are in acceptable understanding. Weight transformation and nature of reaction at various temperature controlled by Thermogravimetric analysis (TGA) and Differential thermal analysis (DTA) respectively. TGA and DTA results demonstrated that as temperature increases the material shifts towards thermal stability and phase purity. Results uncovered that EDTA surfactant helps in diminishing particle size as well as controlling in particles shape and size.
