Application of magnetic nanocomposite Fe3O4 /SiO2/TiO2 in the preparation of phosphines: achieving high efficiency and multi-stage recyclability
This study investigates the application of the Fe3O4/SiO2/TiO2 magnetic nanocomposite for the facile and recyclable production of phosphines. The nanocomposite was fabricated by combining the magnetic properties of Fe3O4, the structural stability of SiO2, and the catalytic activity of TiO2, and was subsequently characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), transmission electron microscopy (TEM), Brunauer–Emmett–Teller analysis (BET), vibrating sample magnetometry (VSM), X-ray photoelectron spectroscopy (XPS), and thermogravimetric analysis (TGA). As a heterogeneous catalyst, this nanocomposite provides high efficiency under mild reaction conditions in phosphine production. Its easy separation using a magnetic field, together with its reusability, makes this approach a sustainable solution in green chemistry. Overall, the findings demonstrate that Fe3O4/SiO2/TiO2 magnetic nanocomposites can significantly contribute to the development of efficient and environmentally friendly industrial processes for phosphine.
