Synthesis and Characterization of Nickel Doped Fe3O4 Nanoparticles Using Solvothermal Method

Over the past 20 years, research on nanomaterials has made remarkable progress not only in the controlled synthesis and the study of novel properties, but also in the multiple applications of matter at the nanoscale. Currently, Fe3O4 magnetite nanoparticles continue to pose an enigma, as the understanding of certain fundamental properties remains unclear despite vigorous efforts and substantial progress in research. In fact, these materials have attracted considerable attention in the fields of new technology with different but complementary motivations using various types of experimental techniques and theoretical approaches. In this work, we present the results obtained from a thorough analysis of Fe3O4 nanoparticles with various Nickel concentrations synthesized through a simple solvothermal method. Characterization methods are mainly structural (XRD, SEM) and physical (UV–Vis, FTIR, …). The SEM images show that the prepared NPs exhibit spherical shape with nanometric size confirmed by X-ray diffraction. Furthermore, the Nickel substitution of iron cations into the crystalline structure had an impact on the average crystallite size. Raman spectra of Fe3O4 magnetite nanoparticles are very consistent with the literature.
