What is it about?
In this article, we review how microreactors very small devices where chemical reactions take place can be designed for processes that use light (photocatalysis), with the added benefit of ultrasound waves. We analyse previous studies to understand which methods work best, what materials are used, and how these systems can be made more efficient and sustainable. Our aim was to provide a clear guide for researchers and developers who wish to apply these technologies to the production of useful compounds or the removal of pollutants in a faster and cleaner way.

Why is it important?
This research is important because it systematically gathers and analyses the available knowledge on how to combine photocatalysis with sonocatalysis to improve the design and performance of microreactors a key technology for cleaner and more efficient processes. What makes it unique is that it not only summarises technical advances, but also identifies best practices, challenges, and opportunities to optimise these systems, bridging theory with real-world applications in areas such as the production of high-value compounds and environmental decontamination. By providing a clear and structured overview, this work becomes a valuable tool to accelerate the development of innovative solutions that harness light and ultrasound to transform chemical processes sustainably.
Perspectives
Writing this article was a fascinating process because it allowed me to explore the intersection of two powerful technologies light and ultrasound and see how they can work together to transform chemical processes. Collaborating with my co-authors to review and connect the many approaches to designing microreactors was both challenging and inspiring, as we realised how much potential there is for innovation in this field. For me, the most rewarding part was turning a highly technical topic into a clear roadmap that can help researchers and industry take the next steps toward cleaner, faster, and more sustainable chemical production. I hope this work motivates others to look at these technologies not in isolation, but as complementary tools for solving complex problems.
