Scientists Susumu Kitagawa, Richard Robson, and Omar Yaghi Win 2025 Nobel Prize in Chemistry for Metal-Organic Frameworks
Stockholm, Oct 8 (TheTrendingPeople.com) — In a landmark announcement on Wednesday, the 2025 Nobel Prize in Chemistry was awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for their pioneering work on metal-organic frameworks (MOFs)—molecular constructions with large, porous spaces capable of storing gases, catalysing chemical reactions, and even harvesting water from desert air.
The laureates’ research has unlocked vast potential in energy, environmental, and chemical sciences, creating materials that can capture carbon dioxide, store toxic gases, or remove pollutants from water.
The Laureates and Their Backgrounds
The winners represent a global contribution to chemistry:
- Susumu Kitagawa, 74, is a professor at Kyoto University, Japan. He has focused on advancing the practical applications of MOFs for sustainable energy and environmental solutions.
- Richard Robson, 88, a professor at the University of Melbourne, Australia, began his MOF research inspired by the crystal structure of diamonds.
- Omar M. Yaghi, 60, a Jordanian-American professor at University of California, Berkeley, is renowned for his work on molecular design and reticular chemistry.
At a press conference, Kitagawa expressed his honour, saying:
“My dream is to capture air and separate air to—for instance, CO2, oxygen, or water—and convert this to useful materials using renewable energy. I tell my students that challenge is very important in chemistry, in science.”
Yaghi, who was born to Palestinian refugees in Jordan, shared his personal journey:
“It's quite a journey and science allows you to do it. Science is the greatest equalising force in the world. Since I was 10, when I found a book on molecules in the library, I chose to investigate problems based on the beauty of molecules. I set out to build beautiful things and solve intellectual problems. The deeper you dig, the more beautifully you find things are constructed.”
Robson, born in Britain and later moving to Australia in his late 20s, was inspired by diamond structures and the potential of molecular frameworks with cavities.
What Are Metal-Organic Frameworks?
Metal-organic frameworks (MOFs) are crystalline compounds made from metal ions connected to organic molecules, creating open, lattice-like structures with extremely high surface areas. These frameworks are porous, enabling gases, liquids, and chemicals to pass through and interact with the internal surfaces.
Some of the key features and applications of MOFs include:
- Gas storage and separation: MOFs can selectively capture carbon dioxide, hydrogen, or methane, potentially reducing greenhouse gas emissions.
- Water harvesting: Certain MOFs can extract water from arid air, offering solutions for regions facing water scarcity.
- Catalysis: MOFs can facilitate chemical reactions, improving efficiency in industrial processes.
- Pollution control: MOFs can remove PFAS and pharmaceutical residues from water systems, addressing environmental contamination.
- Toxic gas storage: MOFs can safely store hazardous gases for later disposal or neutralisation.
“Metal-organic frameworks have enormous potential, bringing previously unforeseen opportunities for custom-made materials with new functions,” said Heiner Linke, Chair of the Nobel Committee for Chemistry.
Since their inception, chemists worldwide have synthesized tens of thousands of MOFs, each designed for specific functions, reflecting the transformative impact of the laureates’ work.
The Journey of Discovery
The path to the 2025 Nobel Prize began decades ago:
- Richard Robson first conceptualized the idea in 1989, combining copper ions with a four-armed organic molecule to create pyramid-shaped molecules that linked into crystals with cavities. While the structures were initially unstable, they provided a foundation for future research.
- Susumu Kitagawa advanced MOFs by stabilizing their structures and exploring practical applications for energy and environmental solutions.
- Omar Yaghi expanded the field through reticular chemistry, systematically constructing frameworks to achieve desired chemical properties and stability.
Their combined efforts turned MOFs from fragile molecular curiosities into robust, versatile materials with broad applications.
Global Impact and Applications
The applications of MOFs are far-reaching and hold potential to address some of humanity’s most pressing challenges:
- Climate Action: MOFs can capture and store carbon dioxide, contributing to efforts to mitigate climate change.
- Water Scarcity Solutions: MOFs that extract water from air offer clean water access in arid regions and desert areas.
- Environmental Remediation: By removing harmful PFAS and pharmaceuticals from water, MOFs help protect ecosystems and human health.
- Energy Storage and Catalysis: MOFs are used in hydrogen storage, chemical catalysis, and fuel cell technologies, enhancing renewable energy applications.
- Industrial Chemistry: MOFs provide customizable solutions for chemical production, improving efficiency while reducing waste.
“The deeper you dig into these frameworks, the more beautifully you find things are constructed,” said Yaghi, emphasizing the elegance and potential of molecular design.
Personal Stories Behind the Laureates
Each laureate’s personal journey reflects resilience, curiosity, and dedication to science:
- Omar Yaghi grew up in a one-room home in Jordan, sharing space with the family’s cattle. His parents had limited formal education, yet Yaghi’s curiosity about molecules propelled him into a career that reshaped chemistry.
- Susumu Kitagawa emphasized the importance of challenge in science, inspiring the next generation of chemists to explore innovative solutions for energy and environmental problems.
- Richard Robson transformed his fascination with diamonds into a method to create highly organized, porous molecular frameworks.
Their diverse backgrounds illustrate how science acts as a global equalizer, enabling innovation regardless of circumstances.
Significance for Science and Society
The recognition of MOFs with the 2025 Nobel Prize in Chemistry underscores their significance in tackling environmental, energy, and technological challenges:
- MOFs offer clean energy solutions, from hydrogen storage to more efficient chemical catalysis.
- They enable sustainable water harvesting, critical for areas facing climate-driven droughts.
- Their ability to trap greenhouse gases provides tools in the fight against climate change.
- MOFs can improve public health by removing pollutants from water and air.
“Following the laureates’ discoveries, the possibilities for custom-made materials are virtually limitless,” Heiner Linke noted, highlighting the revolutionary potential of their research.
Experts believe that continued development of MOFs could transform industries, from pharmaceuticals and chemicals to renewable energy and environmental remediation.
Looking Forward: The Future of MOFs
The 2025 Nobel Prize winners have laid the foundation for a new era in chemistry, with MOFs acting as versatile tools for scientists, engineers, and policymakers. Future research is expected to:
- Expand MOFs for large-scale carbon capture technologies.
- Improve water-harvesting systems in desert and drought-prone regions.
- Enable smarter catalysis for industrial chemical processes.
- Enhance environmental protection technologies, removing emerging pollutants.
As Kitagawa noted, MOFs demonstrate how fundamental chemistry research can directly benefit society, bridging molecular science with practical solutions for global challenges.
