A starch-assisted innovative synthesis of spinel-structured and ferromagnetic behaviour of Fe3O4 nanoparticles catalytic activity evaluated in the selective oxidation

In this research work, for several temperature based on Fe 3 O 4 nanoparticles had been prepared by the sol–gel approach. The physicochemical properties of these catalysts were characterized by the X-ray diffraction (XRD), scanning electron microscopy, transmission electron microscopy (TEM), diffused reflectance spectra, photoluminescence spectroscopy (PL) and vibrating sample magnetometer. Fe 3 O 4 nanoparticles, TEM images and the XRD analysis designated that the chain-like Fe 3 O 4 has a crystal phase of cubic lattice by way for a mean measurement of around 25 nm. The effect of catalyst and solvent on the catalytic oxidation of benzyl alcohol using the Fe 3 O 4 catalyst prepared by sol–gel method was also investigated.
