Structural and Magnetic Investigation of Bi2S3@Fe3O4 Nanocomposites for Medical Applications

Abstract

Bi 2 S 3 and Fe 3 O 4 nanostructures as well as Bi 2 S 3 @Fe 3 O 4 nanocomposites were produced using hydrothermal synthesis. Scanning electron microscopy (SEM), energy dispersive spectra (EDS) and X-ray diffraction (XRD) were used in the characterization of the nanocomposites. The effect of heat treatment on chemical, physical and magnetic properties of the nanostructures was investigated in this study. It was determined that the duration of heat treatment affects the size and shape of the nanostructures. Bi 2 S 3 samples produced using less than 12 h of heat treatment formed in nanoflower-like shapes whereas when the heat treatment was extended to 24 h, the samples formed in nanoribbon-like shapes. The study concludes that an increase in the duration of heat treatment enhances the saturation value of magnetization of Fe 3 O 4 nanostructures.

Synthesis and Characterization of ZnO@Fe3O4 Composite Nanostructures by Using Hydrothermal Synthesis Method

“…In their magnetic saturation measurements of Fe3O4@Bi2S3 nanoflowers synthesized by the hydrothermal method, Yetim et al, found a value of 89.8 emu/g for the Fe3O4 nanostructure [17]. In a similar study, Karacam et al reported the magnetic saturation values of the Fe3O4 nanostructures as 87.7 emu/g and 90.7 emu/g [18]. The magnetic value of the ZnO additive obtained in this study decreased considerably.…”

“…The precipitate was kept at 80 ⁰C for 12 hours (ZnO@Fe3O4-1:1). The same procedures were repeated for 0.656 g of Fe3O4.7H2O and 3.2 g of NaOH (ZnO@Fe3O4-1:2) [17][18][19]. Also, such process are illustrated schematically in Fig.…”

“…Hydrothermal method is a highly efficient production process with minimum production cost which enables researchers to control nanostructure morphology. The method also provide good nanostructure size and shape control [19].…”

Electrical, Optical and Magnetic Studies of Flower Shaped Fe3O4@Bi2S3 core shell Hierarchical Structure

“…These core shell nanocomposite may act as a promising material photo thermal therapy and magnetic hyperthermia application. [12].N.K yeitim et alhave shown the structural and catalytic properties of Fe3O4 doped Bi2S3 nanocomposite using hydrothermal method and they have observed that these nanocomposite have the potential to be used in the waste water treatment [13].Furthermore, the fabrication of these core shell nanomaterial's are usually a complicated process ,that takes a lot of time and occurs at an elevated temperature. Although lot of work has been researched related to this core shell material but very less work has been reported in the magneto optical fiber sensing application of the core shell material.…”
