چکیده
This study reports the successful synthesis of Mg, Fe, and Zn Co-doped TiO2 nanoparticles via a rapid heating technique, exhibiting enhanced sono-photocatalytic activity under both visible and UV light irradiation. Various characterization methods, including X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), and diffuse reflectance UV-vis spectroscopy (UV-DRS), were employed to assess the produced materials. The codoping process led to a significant reduction in the band-gap energy from 3.16 eV to 2.60 eV, facilitating the absorption of visible light and improving the generation of reactive oxygen species. The sono-photocatalytic activity of the Co-doped TiO2 nanoparticles was evaluated by degrading methyl orange solutions, achieving a remarkable degradation efficiency of 48.7% under visible light and 60.1% under UV light. The combined effect of ultrasound and light irradiation synergistically boosted the photocatalytic activity, outperforming each method individually. The Co-doped TiO2 nanoparticles demonstrated a higher efficiency compared to previous investigations, highlighting their potential as a novel visible-light sonophotocatalyst for environmental remediation applications.
