Effect of precursors on chemical composition, morphology, and dimension size of Iron oxide

Iron oxides nanostructures have a wide range of applications in different fields. Properties of nanostructures depend on their size, morphology and chemical composition. The precipitation method is one of the most known and advantageous techniques for the synthesis of metal oxide nanoparticles. To investigate the effect of precursor on properties of iron oxide nanostructures, iron oxide has been synthesized using precipitation method with iron (III) acetate, iron (III) chloride and iron (III) nitrate as the iron precursor. The products were characterized by X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM). Hematite Nanorods were obtained using acetate precursor with uniform shape and lack of agglomeration. Chloride and nitrate precursors were led to the formation of Wuestite and magnetite phase, respectively. In the case of using chloride and nitrate precursors, nanoparticles existed with bulk structures. FTIR spectra of all samples showed strong absorption peaks of Fe-O bond vibration at 400-600 cm-1. This study provides good insights into the synthesis of engineered iron oxide nanostructure with desired properties for different applications.

Synthesis and Characterization of Fe3O4 Nanoparticles Using Different Experimental Methods

IOP conference series, 2020

This paper reports a comparative study on the synthesis of Fe3O4 nanoparticles using three different methods, namely; Co-precipitation, Sonochemical and Solvothermal methods. Ferric chloride hexahydrate (FeCl3.6H2O) and Ferrous chloride tetrahydrate (FeCl2.4H2O) were used as the iron precursor for the Co-precipitation method; while, Ferrous sulphate Heptahydrate (FeCl2.7H2O) and Ferric chloride hexahydrate (FeCl3.6H2O) were used as the iron precursor for sonochemical and solvothermal synthesis methods, respectively. The effect of the experimental methods and the precursors used on the shape and size of the Fe3O4 nanoparticles were investigated using different characterization techniques. The chemical characterization of the samples were carried out using EDX. The size of the nanoparticles were determined using particle size analyzer. The SEM and TEM images were used study to the surface morphology of the produced nanoparticles. Finally, TGA was used to study the thermal stability of the prepared iron oxide nanoparticles.

Synthesis, Characterization and Applications of Magnetic Iron Oxide Nanostructures

Arabian journal for science and engineering, 2017

Iron oxide is a mineral compound that shows different polymorphic forms, including hematite (α-Fe 2 O 3), magnetite (Fe 3 O 4) and maghemite (γ-Fe 2 O 3). Solid propulsion technology nanoparticulate materials, such as hematite and maghemite, exhibit high performance on thermal decomposition of ammonium perchlorate. The enhanced catalytic effect of metallic iron oxide nanoparticles is attributed to their particle size, more active sites and high surface area, which promotes more gas adsorption during thermal oxidation reactions. Nowadays, metallic iron nanoparticles can be synthesized via numerous methods, such as co-precipitation, sol-gel, microemulsion, or thermal decomposition. Although there are data on these synthetic methods in the literature, there is a lack of details related to nanoparticulate oxides and to their characterization techniques. In this context, this short review based on scientific papers, including data from the last two decades, presents methods for obtaining nanoparticulate iron oxides as well as the main aspects of the different characterization techniques and also about the decomposition aspects of these nanomaterials. Morphologies and structures of iron oxides can be characterized through transmission electron microscopy, scanning electron microscopy, X-ray powder diffraction, and Fourier transform infrared spectroscopy. As for textural properties, they are usually determined by physical adsorption techniques.

Solventless synthesis, morphology, structure and magnetic properties of iron oxide nanoparticles

Solid State Sciences, 2017

In this study we report the solventless synthesis of iron oxide through thermal decomposition of acetyl ferrocene as well as its mixtures with maliec anhydride and characterization of the synthesized product by various comprehensive physical techniques. Morphology, size and structure of the reaction products were investigated by scanning electron microscopy, transmission electron microscopy and X-ray powder diffraction technique, respectively. Physical characterization techniques like FT-IR spectroscopy, dc magnetization study as well as 57 Fe Mössbauer spectroscopy were employed to characterize the magnetic property of the product. The results observed from these studies unequivocally established that the synthesized materials are hematite. Thermal decomposition has been studied with the help of thermogravimetry. Reaction pathway for synthesis of hematite has been proposed. It is noted that maliec anhydride in the solid reaction environment as well as the gaseous reaction atmosphere strongly affect the reaction yield as well as the particle size. In general, a method of preparing hematite nanoparticles through solventless thermal decomposition technique using organometallic compounds and the possible use of reaction promoter have been discussed in detail.
