Özet
Background: The search for new magnetic nanomaterials continues for many solution-oriented applications such
as material science, surface science, coating technology, surface engineering, battery, energy storage, catalyst
and adsorption. Magnetic nanomaterials have a wide and effective range of applications in solving many
problems. While nanomaterials have found solutions to many problems, the production processes of these materials have increased concerns about the natural balance of the environment and human health. The concepts of
“green chemistry” and “sustainable materials” find solutions to these concerns. In this study, new magnetic
nanomaterials were produced with the approaches of “green chemistry” and “sustainable material”. Considering
the physical and chemical properties of these magnetic nanomaterials, they are potential candidate materials that
can be used in different applications.
Methods: Fe3O4 magnetic nanomaterials were synthesized through co-precipitation and then Fe3O4 magnetic
nanomaterials were coated with silica (Fe3O4@SiO2) using sol–gel (Stober ¨ process) method. Subsequently,
Fe3O4@SiO2 magnetic nanomaterials were bonded with organic functional group containing amine (Fe3O4@SiO2@L-Pro). Finally, Fe3O4@SiO2@L-Pro magnetic nanomaterials were immobilized with transition metals
(Fe3O4@SiO2@L-Pro-X, (X = Co, Mn, Cu, Ni)). Magnetic nanomaterials were characterized by various spectroscopic techniques (VSM, SEM, SEM-EDX, TGA, DTA, FT-IR, UV–Vis.Spect., XRD, BET,) analyzes revealed that the
production of magnetic nanomaterials was carried out successfully.
Significant findings: Fe3O4@SiO2@L-Pro-X (X = Co, Mn, Cu, Ni) is new products. The magnetic nanomaterials
produced in this study were found to be capable of magnetic property, superparamagnetic character, mesopore
character, suitable surface area, visible-light active character, crystalline cubic spinel form, thermal/mechanical
stability.
