Özet
In this study, flower-like NiO structures were synthesized by hydrothermal method. Then, Fe3O4 was doped onNiO that NiO structures gain magnetic properties. TEM (Transmission Electron Microscopy) and SEM(Scanning Electron Microscopy) were used to assess the morphology of the NiO structures. XRD (X-rayDiffraction) was used to evaluate the crystal structures of the NiO structures. Magnetic properties of the NiOstructures were investigated using VSM (Vibrating Sample Magnetometry). Catalysis properties of the producedstructures were assessed use of products as catalyst in the reduction of 4-nitrophenol (4-NP) was examined.Especially NiO and Fe3O4 were found to exhibit excellent catalytic performance for nitrophenol reduction, whileNiO@Fe3O4 magnetic microflowers were found to exhibit very low catalytic activity.
