What is it about?
In this work, we studied how certain materials made of titanium and with very small structures can use light to transform a molecule called benzyl alcohol into another more valuable molecule called benzaldehyde. We wanted to understand not only whether the reaction works, but also how and why it occurs, what steps it follows, and what particles or species are involved. To achieve this, we combined experiments with different types of light and materials, along with computer calculations. This allowed us to discover details that normally go unnoticed and that help explain how to improve these types of processes to make them more efficient and environmentally friendly.

Why is it important?
This research is not limited to measuring end results, but thoroughly explores the intermediate steps, active species, and conditions that control efficiency and selectivity. Its approach combines experiments under different types of light with computational simulations, allowing us to see the reaction ‘from the inside’ and reveal aspects that previously went unnoticed. This opens the door to designing more precise and sustainable photocatalysts capable of producing valuable compounds in a cleaner and more controlled manner.
Perspectives
Writing this article was both challenging and exciting because it allowed us to go beyond the usual surface-level analysis of photocatalytic reactions and really dig into what is happening at the molecular level. Working closely with colleagues who share the same curiosity about light-driven chemistry made the process even more rewarding. For me, the most satisfying part was realizing that our findings could help bridge the gap between fundamental science and practical applications turning complex mechanisms into tools for designing cleaner, more selective chemical processes. I hope readers find in this work not only solid data, but also inspiration to keep asking “what’s really going on?” in their own research.
