Iron oxide nanoparticles were synthesis by reverse micelle method. X-ray diffraction technique and vibration sample magnetometer were applied to characterize the produced samples at different conditions and parameters for synthesis route. There is no significant difference between samples prepared at 5°C and room temperature except a better crystalline at room temperature. The molar ratio of water to surfactant (w parameter) and concentration of the salt solution on size and magnetic properties of nanoparticles have been investigated. Increasing w leads to producing particles with larger size i.e. for w=16.83, 11.22, and 5.6, particles size are 15.22, 11.66 and 10.5 nm, respectively. The size of nanoparticles are in the range of 9 to 20 nanometers

Abstract In this research, iron oxide nanoparticles were prepared by green synthesis and identified by scanning electron microscopy, X-ray diffraction, infrared spectroscopy, and vibrational magnetometer. The tea leaves extract was used as a reducing agent to synthesize iron oxide nanoparticles. The systematic study of the process was performed using Design Expert 10 software to determine the relationship between the four process variables, namely iron concentration, extract volume, time, and temperature effect. The square model was significant for the response variables. The iron oxide nanoparticles had super-magnetic properties. Then, iron oxide nanoparticles were used for magnetization of activated carbon (MAC). Finally, the MAC were used for phenol removing by response surface methodology (RSM) method. The results manifested that the generated MAC is quite effective in removing phenol. Various parameters such as pH, extraction time and adsorbent amount were optimized by the RSM method. The absorption of phenol was measured by using a spectrophotometer at a maximum wavelength of 510 nm. It was also indicated that phenol in an aqueous solution was removed up to 98%.

Antibacterial Studies

The glycerol iron oxide nanoparticles (GIO-NPs) were obtained by an adapted coprecipitation method. The X-ray diffraction (XRD) studies demonstrate that GIO-NPs were indexed into the spinel cubic lattice with a lattice parameter of 0.835 nm. The refinement of XRD spectra indicated that no other phases except maghemite were detected. The adsorption of glycerol on iron oxide nanoparticles was investigated by Fourier transform infrared (FTIR) spectroscopy. On the other hand, this work implicated the use of GIO-NPs in antibacterial studies. The results indicate that, in the case ofP. aeruginosa  1397biofilms, at concentrations from 0.01 mg/mL to 0.625 mg/mL, the glycerol iron oxide inhibits the ability of this strain to develop biofilms on the inert substratum.

Superparamagnetic Properties

Iron oxide nanoparticles were synthesized by precipitation in isobutanol with sodium hydroxide and ammonium hydroxide. The isobutanol played a role of a surfactant in the synthesis. The nanoparticles were calcined for 100 min to 5 hours in the range of 300 to 600°C. The characterization of the samples by FTIR (Fourier-transform infrared) and XRD (X-ray diffraction) confirmed the formation ofγ-Fe2O3(maghemite) from Fe3O4(magnetite) at calcination at 300°C. The morphology and particle size were studied by SEM (scanning electron microscope). Nanoparticles in the range of 11–22 nm prepared at 0.09 M of ferrous chloride exhibited superparamagnetic properties. Nanoparticles synthesized with ferrous chloride and ammonium hydroxide at 75°C and calcined at 530°C for 2 h wereα-Fe2O3(hematite).

Abstract In this report, aqueous phase green synthesis of iron oxide nanoparticle utilizing Platanus orientalis is elucidated for the first time. The phytoconstituents of the P. orientalis leaf extract serve a dual role as reducing and capping agent during the fabrication of iron oxide nanoparticles. The role of the leaf extract in the synthesis of iron oxide has been briefly demonstrated in this work. The tailored iron oxide particles were characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis, infrared spectroscopy, ultraviolet-visible spectroscopy, and dynamic light scattering technique. Nonetheless, X-ray diffraction pattern reveals the mixed phase nature of the ensuing iron oxide, i.e. α-Fe2O3 and γ-Fe2O3. The spherical oxide particles have an average diameter of 38 nm as determined from transmission electron microscopy. Infrared spectroscopy results confirmed the stabilization of iron oxide nanoparticles by the phytochemicals present in the leaf extract. Iron oxide nanoparticles show significant antifungal activity against Aspergillus niger and Mucor piriformis, employed as model fungi, but found to be more active toward M. piriformis.

Nano-crystalline Fe3O4 particles has been synthesized by chemical co-precipitation method. The synthesized samples were annealed at different temperature 300 °C, 500 °C, 700 °C. The effect of annealing temperature on structural properties of synthesized sample has been studied by various analytical techniques like X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope and Fourier transform infrared spectroscopy (FTIR). The X-ray diffraction patterns confirm the synthesis of single crystalline phase of Fe3O4 nanoparticles. The crystallite size of synthesized iron oxide nanoparticles is about 7 nm. The crystallinity of iron oxide nanoparticles is enhanced by annealing treatment which is also confirmed by corresponding SEM and TEM micrographs. A phase transition from magnetite (Fe3O4) to hematite (α-F2O3) is observed when the samples are annealed above 500 °C. The fundamental groups of the iron oxide and annealed samples have been identified from FTIR spectrum. The particle size calculated from TEM images for the Fe3O4 sample varies in the range 5–20 nm and it has been observed that the particle size increases on annealing.
