Hydrothermal Synthesis of Mixed Nanocomposite of α-[Fe2 O3 -FeOOH] from Iron Nitrate Salt in Teflon Autoclave

Alpha type Fe2O3-FeOOH nanocomposite was synthesized by hydrothermal method and characterized using some spectroscopic methods of analysis. X-ray diffraction (XRD) scanning electron microscopy SEM), elemental diffraction X- ray (EDX) and transmission electron microscopy (TEM) methods were used to characterize the synthesized nanocomposite. XRD analysis shows that the single-crystalline phase of the nanomaterial was formed while the zeta potential analysis indicated 20.0 mV respectively. The morphology and shape of the synthesized mineral was studied with SEM and TEM while the elemental analysis was done with EDX. SEM and TEM analysis show that the synthesized alpha Fe2O3-FeOOH nanomaterils were rod-like in shape while EDX analysis gave a good composition of the elements of the synthesized material. The average crystal size of the synthesized α-[Fe2O3-FeOOH] estimated by Debye-Scherer equation to be 56.78 nm which confirms the nanosize of the material.
