What is it about?
This article reviews how sonophotocatalysis a process that combines light and ultrasound can be used to degrade pollutants in water and air. It explains the scientific basis, the role of catalysts like TiO₂, and summarises experimental results from different studies. The focus is on showing how the synergy between sound waves and light creates more efficient chemical reactions to eliminate contaminants that are otherwise hard to remove.

Why is it important?
This research is important because it highlights a promising and environmentally friendly method for tackling pollution. Its uniqueness lies in presenting sonophotocatalysis not just as two separate techniques but as a powerful combined approach with enhanced efficiency. By systematically reviewing applications, challenges, and future perspectives, it provides a roadmap for developing sustainable technologies to clean water and air problems of global importance.
Perspectives
Writing this article was a rewarding experience because it allowed us to bring together knowledge from different fields photocatalysis, sonochemistry, and environmental engineering to show how they can complement each other. For me, the most meaningful part was realising that by merging these methods, we can design practical solutions for one of today’s most pressing challenges: pollution. I hope this work inspires others to explore innovative approaches that make environmental remediation not only more effective, but also more sustainable.
