In conclusion, the study demonstrates that tri-doping TiO₂ with boron, cerium, and silver can significantly enhance photocatalytic activity, with B1Ce1Ag0.1TiO₂ emerging as the most effective catalyst among those tested. While the performance under UV-A irradiation was moderate, the results highlight the potential of these materials for visible and solar light-driven photocatalytic applications. Moving forward, optimizing the synthesis process, exploring broader light spectra, and conducting large-scale tests will be crucial to realizing the practical application of these catalysts for wastewater treatment and combating antibiotic pollution. By addressing these challenges, tri-doped TiO₂ photocatalysts could become a cornerstone technology in the fight against AMR and environmental contamination, paving the way for cleaner, safer water systems.
