The Royal Swedish Academy of Sciences awarded the 2025 Nobel Prize in Chemistry to Susumu Kitagawa, Richard Robson and Omar Yaghi for their work on metal–organic frameworks (MOFs). These lattice-like materials have spacious pores that allow gases and chemicals to flow through them. MOFs can be engineered to trap carbon dioxide from power plants and factories and to break down pollutants, making them promising tools against climate change and environmental contamination.

The Nobel committee described the research as "molecular architecture", noting that the three scientists independently developed ways to build MOFs by connecting metal atoms with organic molecules. Their discoveries laid the foundation for a fast‑growing field of chemistry. Experts say MOFs could one day help capture greenhouse gases and store valuable chemicals more efficiently.
