Abstract

For the photocatalytic degradation of dye, ternary metal oxides (SrFe12O19/TiO2/SiO2) and their nanocomposites with graphene oxide were produced using the Sol-gel and Hummers’ process, respectively. UV–Vis diffuse reflection spectroscopy (DRS) revealed that the samples a low band gap of 2.29 eV. The reduced band gap of SrFe12O19/TiO2/SiO2/GO resulted in significantly enhanced photocatalytic activity compared to the bare photocatalysts. The calcined samples of SrFe12O19/TiO2/SiO2/GO showed optimal photocatalytic performance, achieving 100% degradation of Alizarin red dye under visible light irradiation within 60 minutes at pH-6 (dye concentration 10ppm). Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were in used to assess the phase purity, structural properties and surface morphology of the prepared nanomaterials and their nanocomposites. Fourier-transform infrared (FTIR) spectroscopy was used to identify the functional groups in the manufactured metal oxides, confirming the presence of M − O (metal-oxygen) bonds. Vibrating sample magnetometry (VSM) was familiar analyze the magnetic properties of the composite particles. The outcomes demonstrated that the SrFe12O19/TiO2/SiO2/GO composite particles consisted of spherical nanoparticles approximately 30 nm in diameter. The antibacterial activity of the nanocomposites was tested against Gram-negative Pseudomonus aeruginosa (ATCC-15692) and Gram-positive Micrococcus luteus (ATCC 9341) bacteria. Moreover, SrFe12O19 nanoparticles possess excellent magnetic properties, which are largely retained in the TSG composite and can be easily separated from suspension by applying a magnetic field. These magnetic composite nanoparticles demonstrated substantial photocatalytic efficiency, making them promising for water remediation.
