The study marks a significant step toward developing advanced photocatalysts for environmental remediation. The tri-doped TiO₂ photocatalysts exhibit promise, particularly with their modified band gap and improved degradation capabilities. However, their moderate performance under UV-A light emphasizes the need for further testing and optimization under visible and solar light to achieve their full potential. As the field of photocatalysis continues to evolve, integrating these advancements into practical systems will play a vital role in addressing critical issues such as water pollution and antimicrobial resistance. By refining these catalysts and expanding their scope, this research lays the groundwork for sustainable solutions that align with global efforts to protect the environment and public health.
