The catalyst could be easily recovered in the presence of the external magnetic field and reused five times without significant loss of activity and mass. The magnetic nanoparticles were characterized using Fourier Transform InfraRed (FT-IR) spectra, X-Ray Diffraction (XRD) spectroscopy, Scanning Electron Microscopy (SEM), Thermal Gravimetric Analysis (TGA). The results showed the spherical structures of hybrid magnetic nanoparticles and the average size is about 37 nm. %U https://ijcce.ac.ir/article_34794_97f6e1b79138a6414b8981feb3560aff.pdf
