“…3 and 4). The energy of band gap for Zn-Fe3O4Nps was found to be 1.9ev (direct band gap) and 1.3eV (indirect band gap), which is smaller than bulk Fe3O4NPs [18]. The outcome confirmed that zinc metal ion plays a significant role to reduce the energy band gap of the magnetite nanoparticles.…”

Objective: Magnetite (Fe3O4) nanoparticles (NPs) have gained considerable attention in the Biomedical filed. Evolution of new magnetic material based on the transition metal-doped magnetite has become the subject of increasing research interest. The main aim of the current investigation was to improve the diabetic potential, optical, magnetic, structural properties of magnetite nanoparticles and hence Fe3O4 NPs were doped with a divalent transition element such as Zinc. Methods: Zinc doped magnetite nanoparticles (Zn-Fe3O4 NPs) were obtained through Co-precipitation methods using aqueous plant extract of Andrographis paniculata acted as an efficient stabilizer and a reducing agent. The structure, morphology, crystalline, optical and magnetic property of synthesized Zn-Fe3O4 NPs were evaluated by X-ray diffraction (XRD), Scanning electron microscopy with Energy dispersive x-ray spectroscopy(SEM-EDX), Fourier transform infrared spectroscopy (FTIR), Ultraviolet-Visible (UV-Vis) Spectrophotometer and Vibrating scanning magnetometer (VSM). Results: In XRD analysis, the average crystallite size of the synthesized Zn-Fe3O4 NPs was found to be 5 nm exhibiting super paramagnetic behavior, which composes it an appealing possibility for biomedicines. The Zn-Fe3O4 NPs had strongly inhibited the alpha (α)-amylase enzyme and had proved their therapeutic role. Conclusion: In conclusion, Zn-Fe3O4 NPs is an excellent anti-diabetic agent to control type 2 diabetes mellitus.

Synthesis of Fe3O4/ZnO-Cu nanocomposite photocatalyst has been conducted. The synthesis was carried out using the co-precipitation method with the variation of Cu concentration and modification by Fe3O4 magnetic material. As synthesized photocatalysts were characterized using FTIR, XRD, TEM, and SR UV-Visible. Photocatalytic activities of samples were evaluated through Rhodamine B degradation under visible light irradiation. The results showed that a sample with Fe3O4/ZnO-Cu 1% has smaller band gap energy of 2.90 eV and the highest photocatalytic activity than pure ZnO or Fe3O4-modified ZnO (Fe3O4/ZnO-Cu 0%) under visible light. The percentage of Rhodamine B degradation was approximately 89.41% during 120 min of visible light illumination. Moreover, the photocatalyst materials could be easily separated after photocatalysis which is due to the magnetic property of Fe3O4 material. Therefore, Cu-doped ZnO with Fe3O4 modification has been an efficient and effective visible-light-induced photocatalyst in removing non-biodegradable Rhodamine B dyes.
