Synthesis and Characterization of Iron Oxide Nanoparticles by Plant Green Method: a Review

Abstract

The importance of nanomaterials comes from the fact that they possess properties that distinguish them from classical materials, which makes them more efficient in several applications. Therefore, this article discussed one of these nanomaterials, which is nano-iron oxide, and its types (α-Fe₂O₃, γ-Fe₂O₃, and Fe₃O₄) in its particulate form. It focused on the green method and its properties using plant extracts, which are part of a bottom-up methodology for preparing nanomaterials. It also addressed the factors affecting the preparation process, including reaction time, pH, and temperature, through several studies to determine the optimal conditions for preparation. The article then presented the diagnostic techniques used in diagnosing nano iron oxide particles, which are (UV-vis analysis, Fourier transform infrared analysis (FT-IR), X-ray diffraction (XRD), field emission electron scanning microscope (FESEM)) and then reviewed the applications in which the use of nanosized iron oxide was successful, which are toxic organic contamination in the environment, anti-microbial, removal of arsenic from water, antioxidant and anti-radical, and antibacterial
