The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for their pioneering work on metal-organic frameworks (MOFs) — a class of materials that has redefined what is possible in environmental science, energy innovation, and molecular engineering. This year’s prize highlights not only a scientific breakthrough but also a shift toward recognizing chemistry’s power to address urgent global challenges.
Announced by the Royal Swedish Academy of Sciences, the award celebrates decades of research that began with theoretical concepts and has evolved into technologies that can capture carbon dioxide, harvest water from air, and store clean energy sources. The laureates’ contributions stand at the intersection of fundamental chemistry and real-world impact, making this one of the most meaningful Nobel Prizes in Chemistry in recent memory.
A Turning Point in Chemical Science
For more than a century, the Nobel Prizes Chemistry awards have honored discoveries that shaped our understanding of the natural world — from molecular structures to catalytic processes. But in recent years, the prize has increasingly celebrated innovations that connect the laboratory to real-world applications. This year’s recognition of metal-organic frameworks continues that trend.
MOFs are crystalline structures built by linking metal ions to organic molecules, forming intricate, sponge-like networks. The key lies in their extremely high internal surface area: a tiny quantity can have as much inner surface as an entire football field. This unique property allows MOFs to trap, store, and separate gases and chemicals in ways that traditional materials simply cannot.
The Laureates and Their Breakthrough
Richard Robson: The Visionary Foundation
In the late 1980s, Australian chemist Richard Robson envisioned materials with permanent porosity. He was among the first to experiment with linking metal centers to organic structures, creating early porous frameworks. Though these early structures were unstable and difficult to reproduce, they represented the first step toward a new class of materials. Robson’s early insights provided the conceptual blueprint that would later be refined by others.
Susumu Kitagawa: Stabilizing the Structure
Japanese chemist Susumu Kitagawa took these fragile frameworks and gave them stability. His work demonstrated that these networks could hold their shape while absorbing and releasing gases, something that had not been achieved before. This was the critical leap that transformed MOFs from a laboratory curiosity into a promising field of materials science. Kitagawa’s research proved that porous frameworks could function under practical conditions — making them useful for gas storage, separation, and environmental applications.
Omar M. Yaghi: Reticular Chemistry and the U.S. Connection
The story then moved to the United States. Omar M. Yaghi, a Jordanian-born American chemist at the University of California, Berkeley, introduced a methodical way to build these frameworks. He coined the term “reticular chemistry,” describing a systematic approach to designing MOFs using modular building blocks. Like molecular Lego pieces, Yaghi’s approach allowed scientists to create thousands of distinct MOFs with targeted properties — controlling everything from pore size to chemical reactivity.
Yaghi’s lab became a global center of MOF research, positioning the United States at the forefront of this emerging field. His work helped drive an explosion of research across academia and industry, leading to real applications in energy, water, and environmental protection.
Why Metal-Organic Frameworks Matter
MOFs are more than a scientific curiosity — they have the potential to reshape industries and address some of the most urgent issues of the 21st century. Their tunability makes them adaptable to a wide range of uses:
- Carbon Capture: MOFs can selectively capture carbon dioxide from the air or from industrial emissions, offering a path toward cleaner energy and climate mitigation.
- Water Harvesting: Some MOFs can absorb water vapor from desert air and release it when heated, making them promising for water-scarce regions.
- Pollution Control: MOFs can trap persistent chemicals and pharmaceuticals that conventional filters struggle to remove.
- Hydrogen and Gas Storage: Because MOFs can store large amounts of gas at low pressures, they may play a key role in developing hydrogen-based energy systems.
- Chemical Separations and Catalysis: MOFs can act as catalysts or molecular sieves, making industrial chemical processes more efficient and environmentally friendly.
The versatility of MOFs stems from their modularity. By changing the metals or organic linkers, scientists can design frameworks for specific molecules, tailoring each material to its intended purpose.
A Historic Moment for U.S. Science
The Nobel Prizes Chemistry announcement has particular resonance in the United States because of Omar Yaghi’s pivotal role. Yaghi’s win marks the 28th Nobel Prize for UC Berkeley, one of the nation’s most storied research institutions. His journey from student in upstate New York to Nobel laureate at a leading American university reflects the strength of the U.S. academic and research environment.
Yaghi’s laboratory became a training ground for many of the world’s top materials scientists. Numerous companies and research centers in the U.S. have since adopted MOF technologies, investing in applications ranging from clean energy to advanced filtration systems.
The award also underscores how international collaboration fuels scientific progress. With laureates from Australia, Japan, and the United States, this Nobel Prize demonstrates how global science can unite to address shared challenges like climate change and resource scarcity.
From Discovery to Application: Decades in the Making
The journey to the 2025 Nobel Prize in Chemistry spans nearly four decades:
- 1980s: Early porous frameworks are synthesized, but stability issues limit their use.
- 1990s: Breakthroughs in stabilizing frameworks allow for gas adsorption studies.
- 2000s: Reticular chemistry brings precision and scalability, enabling thousands of MOF variations.
- 2010s–2020s: MOFs move from lab to pilot projects, showing real promise in carbon capture, water harvesting, and hydrogen storage.

As research continues, these applications are expected to grow rapidly. The Nobel recognition will likely increase investment and speed up the translation of MOFs from the lab to everyday use.
Challenges on the Horizon
While MOFs hold remarkable promise, several challenges remain before their full potential can be realized:
- Stability: Some MOFs degrade when exposed to moisture, acids, or high temperatures, limiting their industrial use.
- Production Scale: Manufacturing MOFs at low cost and large scale remains technically challenging.
- Integration: Embedding MOFs into devices like filters or reactors requires innovative engineering solutions.
- Regulation and Safety: As MOFs are introduced into environmental and medical applications, regulatory frameworks must adapt.
Addressing these challenges will require interdisciplinary collaboration between chemists, engineers, policymakers, and industries.
