“…In addition, the lack of any impurity peak in the XRD diffraction patterns in these structures indicates that they have high crystallinity. The resulting XRD patterns were seen to be consistent with the ZnO@Fe3O4 nanostructures obtained by different methods in the literature, but they gave better results in terms of impurity [5,6], [20][21][22]. The synthesized SEM images of the ZnO containing different weight ratios of Fe3O4 are shown in Figure 3a and Figure 3b.…”

In this study, ZnO@Fe3O4 composite nanostructures were synthesized using the hydrothermal method. X-ray diffraction analysis was performed for the structural characterization of nanostructures obtained with the addition of Fe3O4 at different ratios, and no impurity peaks were found. Scanning electron microscope (SEM) and transmission electron microscope (TEM) were used for morphological imaging. It was understood that ZnO nanoparticles were decorated around Fe3O4 in the morphology of nanostructures. Fe, Zn, and O peaks were detected in elemental analysis. Energy band gaps of ZnO@Fe3O4 nanocomposite structures were obtained from absorbance data collected by use of UV-VIS spectrometer. The band gap values of nanostructures were calculated to be in the range of 2-2.1 eV. Magnetic properties were determined using a vibrating sample magnetometer (VSM), and the values of 3.76 emu/g and 7.96 emu/g were found depending on the Fe3O4 content. Although these values show a limited ferromagnetic property, they are important in optoelectronic and medical imaging applications due to the advanced optical and electronic properties of ZnO. Hidrotermal yöntem kullanılarakZnO@Fe3O4 kompozit nanoyapıların sentezi ve karakterizasyonu Anahtar Kelimeler Nanokompozit ZnO@Fe3O4, Morfo-yapısal karakterizasyon, Medikal görüntüleme, Manyetik ve optik özellikler Öz: Bu çalışmada, ZnO@Fe3O4 kompozit nanoyapılar hidrotermal yöntem kullanılarak sentezlenmiştir. Farklı oranlarda Fe3O4 katkısıyla elde edilen nanoyapıların yapısal karakterizasyonu için X-ışını kırınım analizi gerçekleştirildi ve herhangi bir safsızlık pikine rastlanmadı. Morfolojik görüntülemede taramalı elektron mikroskobu (SEM) ve geçirimli elektron mikroskobu (TEM) kullanıldı. Nanoyapıların morfolojisinde Fe3O4 etrafında ZnO nano taneciklerinin dekore edildiği anlaşılmıştır. Elemental analizde ise Fe, Zn ve O pikleri kaydedilmiştir. ZnO@Fe3O4 nanokompozit yapıların bant aralığı enerjileri Uv-Vis spektromotresi aracığılıyla elde edilen absorbans datalarından elde edilmiştir. Nanoyapıların bant gap değerleri yaklaşık olarak 2-2.1 eV aralığında hesaplanmıştır. Manyetik özellikler ise Vibrating Sample Magnetometer (VSM) kullanılarak tespit edildi ve Fe3O4 katkı oranına bağlı olarak 3.76 emu/g ile 7.96 emu/g değerleri bulundu. Bu değerler sınırlı bir ferromanyetik özellik göstermesine rağmen ZnO'nun sahip olduğu gelişmiş optik, elektronik özelliklerinden dolayı optoelektronik ve medikal görüntüleme uygulamalarında önem arz etmektedir.

“…In particular, signals associated with the crystalline pattern of goethite are observed in the MZ3 diffractogram. 18 These results are consistent with the lack of magnetic response evidenced by MZ3 according to the data described in section 3.1 and those discussed later. The absence of signals ascribed to the wurtzite structure could be related to the loss of stability and partial dissolution of Z under the synthesis conditions.…”

“…The surface of the zinc oxide nanoparticles is smoothed but when the iron oxide nanoparticles are doped in zinc oxide nanoparticles the smoothness of the zinc oxide nanoparticles was found to reduce. On the other hand, the coating of ZnO nanoparticles on the surface of the magnetite nanoparticles resulted into a bigger clusters or leads to agglomeration [36] as well as reduction in the crystallinity of the nanoparticles.…”

Tri-octyl-amine is known for its potential to assist fabrication of metal and metal oxides nanoparticles. In this work elucidate the synthesis of magnetite-ZnO magnetic nano hybrid by simple one pot reflux method. The synthesized nanoparticles were characterized using X-ray diffraction (XRD), FE-SEM, HR-TEM, vibrating sample magnetometer (VSM), fourier transform infrared spectroscopy (FTIR) and UV-Vis spectroscopy. The X-ray diffraction results confirm the formation of magnetite-ZnO nanocomposites. IR data reveals the characteristic adsorption bands for oxide formation. Magnetic property of the prepared composite was determined by VSM. The photocatalytic activities was performed using methylene blue under UV irradiation. magnetite-ZnO nanocomposite were prepared by using one-pot reflux method with the help of trioctylamine as a solvent and hydrolysing agent.
