The development of efficient photocatalysts for environmental remediation, particularly for the degradation of organic pollutants, has gained significant attention in recent years. This study focuses on the synthesis, characterization, and electrophoretic deposition (EPD) of Fe-doped TiO2 nanoparticles, as well as their application in the sonophotocatalytic degradation of methylene blue (MB), a common organic dye pollutant. The incorporation of iron (Fe) into the TiO2 lattice was aimed at enhancing its photocatalytic activity under visible light by reducing the bandgap and minimizing electron-hole recombination. The synthesized nanoparticles were characterized using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis. The electrophoretic deposition technique was employed to create thin films of Fe-doped TiO2 on conductive substrates for practical applications. The sonophotocatalytic performance of the Fe-doped TiO2 nanoparticles was evaluated by monitoring the degradation of MB under visible light irradiation. The results demonstrated that Fe-doped TiO2 exhibited superior efficiency (92% degradation in 30 minutes), highlighting its potential for wastewater treatment and environmental cleanup. To complete the research, the reusability of the catalyst was also investigated.
