Green synthesis and characterization of Iron oxide Nanoparticles using Ficus carica (common fig) dried fruit extract.
Journal of bioscience and bioengineering, 2018Co-Authors: Derya Aksu Demirezen, Yalçın Şevki Yıldız, Şeyda Yılmaz, Dilek Demirezen YilmazAbstract:Ficus carica (common fig) dried fruit extract was used to synthesize Iron oxide Nanoparticles in this study. Biomaterials in the common fig dried fruit extract synthesized the Iron Nanoparticles by reducing the Iron precursor salt and then acted as capping and stabilizing agents. The Nanoparticles were produced smaller than 20 nm diameters and oxidized due to the high phenolic compound content in the common fig dried fruit extract. Nanoparticles were characterized by energy dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS). First, color change and pH reduction occurred immediately due to the Iron Nanoparticle synthesis. TEM images showed that the Nanoparticles were at 9 ± 4 nm diameters and the metallic core-oxide shell form. The Nanoparticles were in spherical shapes with a monodisperse distribution. EDX, XRD and FTIR analysis signals showed the Iron oxyhydroxide/oxide formation. Absorption peaks were detected at 205 nm and 291 nm due to the Iron metallic core hydrolysis products. The intensity-average diameter of Nanoparticles was calculated at 475 nm diameter by DLS analysis. Colloid stability was determined as moderate at 20.7 mV.

in situ microwave enhanced electrochemical reactions at stainless steel nano Iron for aqueous pollutant degradation
Electrochemistry Communications, 2016Co-Authors: Gema Cabello, Murilo F. Gromboni, Ernesto C. Pereira, Frank MarkeAbstract:Abstract Iron Nanoparticle deposition and stripping are observed from aqueous Fe 2 + solution at pH 3 on stainless electrodes in the presence of focused microwave activation. The effects of Fe 2 + concentration and microwave power are evaluated. It is shown that the resulting Iron Nanoparticle deposit (i) gives well-defined anodic stripping responses, (ii) is readily released into the solution phase, and (iii) is highly reactive towards chlorinated hydrocarbons such as trichloroacetate. The combined effects of increased mass transport and localized microwave heating improve pollutant degradation treatments.
