Scientists created molecular architecture with large spaces to trap harmful gases like CO2 and PFAS, aiding pollution control and breaking down dangerous chemicals
Stockholm
The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa (Kyoto University, Japan), Richard Robson (University of Melbourne, Australia), and Omar M. Yaghi (University of California, US) for pioneering work on metal-organic frameworks (MOFs) — new materials that could help address global challenges such as climate change and pollution.
The scientists developed a method to build molecules into structures with large open spaces, described by the Nobel committee as “molecular architecture.” These spaces can trap and store gases or chemicals, including harmful carbon dioxide and persistent pollutants known as forever chemicals (PFAS). The technology could also be applied to break down dangerous gases, including those used in weapons, and capture carbon emissions from factories and power plants.
Kitagawa described the honour as “deeply delightful” during a press call, adding a humorous note about a meeting he needed to attend. The trio will share 11 million Swedish kronor (£872,000).
Work on MOFs began in the 1970s and 1980s. Robson creatively modelled atoms and bonds in the lab, while Kitagawa was inspired by the idea of “the usefulness of useless,” and Yaghi was driven by fascination with molecular structures from a young age.
The award highlights chemistry’s role in solving urgent global problems. Professor Sheila Rowan of the Royal Society noted that the winners “set the direction for one of the fastest-growing areas of modern chemistry.” Dr Annette Doherty of the Royal Society of Chemistry said such awards show chemistry’s potential to improve healthcare, clean energy, environmental protection, and food and water security.
This is the third major science Nobel announced this week, following awards in Physics and Medicine.
