Building materials on a tiny scale

Three scientists, Susumu Kitagawa, Richard Robson, and Omar M. Yaghi, have won the 2025 Nobel Prize in Chemistry for creating special materials that could help solve some of the world’s biggest environmental problems.

Their invention is called metal-organic frameworks, or MOFs for short. These materials are made by linking tiny metal atoms to organic (carbon-based) molecules, forming structures with countless small holes and spaces inside them. Scientists sometimes call this “molecular architecture” because it’s like designing buildings, but on an incredibly small scale.

Why these materials matter

MOFs can act like tiny sponges that trap gases or chemicals passing through them. This could make them extremely useful for cleaning the planet. Scientists believe MOFs might one day:

• Capture carbon dioxide from the air
• Trap pollution or forever chemicals that harm the environment
• Help store clean fuels like hydrogen
• Make future batteries and medicines safer

These materials are still being tested in laboratories, but their potential is exciting. Some experts think they could become one of chemistry’s most important tools for fighting climate change.

Years of research pay off

The Nobel Prize winners began studying how to build MOFs many years ago, as far back as the 1970s and 80s. Back then, their work didn’t seem very useful at all. But their experiments laid the foundation for today’s research into these powerful materials.

Now, their “useless” ideas have turned out to be incredibly valuable. The three scientists work in Japan, Australia, and the United States, but their discoveries are helping researchers all around the world.

Chemistry that helps the Earth

Every year, the Nobel Prizes celebrate people who use science to make life better. This year’s Chemistry winners remind us that creative ideas and patience can lead to discoveries that protect our planet. MOFs might be invisible to the human eye, but they could make a very visible difference to Earth’s future.
