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

Abstract

In this research work, for several temperature based on Fe3O4 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. Fe3O4 nanoparticles, TEM images and the XRD analysis designated that the chain-like Fe3O4 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 Fe3O4 catalyst prepared by sol–gel method was also investigated.
