In this study, three ternary-doped titanium dioxide (TiO₂) photocatalysts were synthesized using a facile and eco-friendly EDTA-citrate method. The dopants-boron, cerium, and silver-were strategically chosen to enhance the photocatalytic activity of titanium dioxide under UV-A irradiation. These dopants play a vital role in improving light absorption, increasing the surface area, and reducing recombination of electron-hole pairs, thereby boosting the overall efficiency of the catalyst. The synthesized photocatalysts were evaluated for their effectiveness in degrading ciprofloxacin, a commonly used antibiotic, under UV-A light.
