The Nobel Prize in Chemistry 2025 was awarded equally to Susumu Kitagawa of Japan, Richard Robson of Australia and Omar M. Yaghi of the USA for the development of metal-organic frameworks, or MOFs. The official Nobel press release is dated 8 October 2025, and the 11 million Swedish kronor prize was shared equally by the three laureates. It should be read not only as an award-list fact but also as an example of modern materials technology, because MOFs directly connect with applications in gases, water and pollution control.

MOFs are porous crystalline materials in which metal ions are linked by organic molecules. This arrangement creates large internal cavities, making the materials useful for interactions with gases and other chemicals. Some materials such as MOF-5 can have an internal surface area as large as a football pitch in just a few grams. That makes the topic relevant not only to chemistry, but also to environment, energy and materials science.

The listed applications include carbon dioxide capture, water harvesting from desert air, separating PFAS from water, gas storage, catalysis and drug delivery. For exam preparation, this current-affairs update links awards and scientific achievement with water stress, pollution control, climate change, energy security and static GK on new materials. In RAS and UPSC-style papers, it can generate direct factual questions, application-based prelims questions and short mains points on the science-environment interface. Aspirants should remember the laureates, their countries, the reason for the award, the definition of MOFs, major applications and the prize amount together.
