What is it about?
Formaldehyde is a harmful gas commonly found in indoor air, and detecting or removing it is important for health and safety. In this study, we used computer simulations to explore how specially designed carbon molecules called fullerenes, which are shaped like hollow balls, can be modified with metals like iron or nickel to capture formaldehyde. These modified molecules showed strong interactions with formaldehyde, meaning they could work well as tiny sensors or filters. Our results help scientists design better materials for cleaner and safer air.

Why is it important?
This work is unique because it explores, for the first time, the use of transition metal-functionalized porphyrin-like C₇₀ fullerenes for formaldehyde detection and adsorption—an innovative combination of structure and function. The approach offers a novel pathway to design highly sensitive and selective molecular sensors using computational tools. At a time when indoor air pollution and toxic gas exposure are growing global concerns, our findings provide valuable insights that can accelerate the development of next-generation materials for air purification and environmental monitoring.
Perspectives
As a researcher, I’ve always been passionate about finding sustainable and efficient ways to tackle real-world problems like air pollution. This study represents a meaningful step in that direction. Exploring how molecular design and computational chemistry can help create smart materials for detecting harmful gases like formaldehyde was both intellectually rewarding and personally fulfilling. I believe that the integration of nanostructures like C₇₀ fullerenes with transition metals opens up exciting possibilities—not just for sensing technologies, but also for broader environmental applications. I hope this work inspires further research and innovation in this critical field.
