Synthesis, Characterization and Photocatalytic Studies of Novel SrFe12O19/TiO2/SiO2/GO nanocomposite

Sol-gel and Hummers created magnetic SrFe12O19/TiO2/SiO2/GO as a nanocomposite photocatalyst with a high crystalline TiO2 shell. X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), High-resolution transmission electron microscopy (HRTEM), Scanning electron microscopy (SEM), Ultraviolet-visible diffuse reflectance spectroscopy (UV-DRS) and Vibrating sample magnetometer (VSM) were utilized to analyze the composite particles produced. The findings demonstrate that the SrFe12O19/TiO2/SiO2/GO composite particles that were formed, were made up of spherical nanoparticles with a diameter of roughly 30 nm with silica serving as covering and fence between GO, titania shells and several SrFe12O19 small particles with a diameter of around 20 nm serving as cores. It exhibits a band gap energy. The value is 2.29 eV. Under UV irradiation, the composite photocatalytic particle's photocatalytic activity was also examined for the breakdown of Rhodamine B and Methylene Blue under UV light, 100% of the dyes degrade in 60 and 70 minutes when magnetic composite nanoparticles were present. Using magnetic separation, the created magnetic composite nanoparticles showed significant photocatalytic efficiency and could be utilized for remediating contaminated water.
