Nobel Prize in Chemistry 2025

The Nobel Prize in Chemistry 2025 has been awarded to Susumu Kitagawa (Japan), Richard Robson (Australia), and Omar Yaghi (US) for their pioneering work in the creation and development of Metal-Organic Frameworks (MOFs), a groundbreaking class of materials with immense potential across multiple industries.

1. Creation of Metal-Organic Frameworks (MOFs):

• Richard Robson:

  • Robson was one of the first scientists to design 3D structures by combining metal ions (e.g., copper) with organic molecules, creating strong, interconnected frameworks.

  • He demonstrated that it is possible to build materials with large internal spaces capable of trapping molecules, thereby laying the foundation for the development of porous materials.

• Susumu Kitagawa:

  • Building on Robson's work, Kitagawa discovered that these porous structures could not only remain stable but also have the remarkable ability to expand and contract in response to external gases or chemicals.

  • This adaptability allowed MOFs to be used in practical applications like gas capture (e.g., carbon dioxide) and energy storage, making them highly versatile.

• Omar Yaghi:

  • Yaghi is credited with coining the term Metal-Organic Frameworks (MOFs) and was instrumental in developing reticular chemistry, a systematic approach to assembling metal ions and organic molecules into large, well-ordered structures.

  • His contributions included rationally designing MOFs to have specific properties and functionalities, such as optimized pore sizes and selectivity for different gases, paving the way for numerous applications in environmental and industrial solutions.

2. What are Metal-Organic Frameworks (MOFs)?

• MOFs are crystalline materials composed of metal ions linked by organic molecules, forming porous structures with tiny, well-organized holes (pores).

• These materials have exceptionally high surface areas and can be engineered to trap, store, or filter gases and chemicals, making them highly effective for applications that require selective adsorption or storage.

3. Significance of MOFs:

• Water Harvesting:

  • MOFs have the ability to extract water from desert air, potentially providing a solution to water scarcity, particularly in arid regions.

• Carbon Capture:

  • Certain MOFs can selectively attract and store carbon dioxide (CO₂), offering a powerful tool in the fight against climate change by reducing the concentration of CO₂ in the atmosphere.

• Storage of Toxic Gases:

  • MOFs can be used to safely trap harmful chemicals or toxic gases, making them useful in environmental cleanup and chemical storage.

• Custom-Designed Chemical Processes:

  • The highly customizable nature of MOFs allows them to be engineered for specific chemical reactions or storage needs, opening doors to tailored solutions for a range of industrial applications, from energy storage to pharmaceuticals.

Indian Nobel Laureate in Chemistry:

• Venkatraman Ramakrishnan, an Indian-born scientist, was awarded the Nobel Prize in Chemistry in 2009, along with Thomas A. Steitz (US) and Ada E. Yonath (Israel), for their groundbreaking studies on the structure and function of the ribosome, a key molecular machine involved in protein synthesis.

The Nobel Prizes:

The Nobel Prizes are prestigious international awards given annually to individuals or organizations that have made outstanding contributions to humanity in various fields. These prizes were established by the will of Alfred Nobel, a Swedish chemist, engineer, and inventor, who sought to use his fortune to reward those who had brought the "greatest benefit to mankind."

The Nobel Prizes were first awarded in 1901 and have since become a symbol of excellence and global recognition in their respective fields.

Each Nobel Prize laureate receives:

• A gold medal, symbolizing their honor and achievement.

• A diploma, personally signed by the awarding institution.

• A cash award, which varies annually depending on the funds of the Nobel Foundation. For instance, in 2023, the cash prize was about 11 million Swedish kronor (approximately 1 million USD).

Summary:

The Nobel Prize in Chemistry 2025 honors three scientists — Susumu Kitagawa, Richard Robson, and Omar Yaghi — for their innovative work in the development of Metal-Organic Frameworks (MOFs). These materials have revolutionized the way we approach energy storage, gas capture, water harvesting, and chemical processes.
