10月8日,瑞典皇家科学院宣布,将2025年诺贝尔化学奖授予日本京都大学北川进、澳大利亚墨尔本大学理查德·罗布森和美国加州大学伯克利分校奥马尔·亚吉,以表彰他们在“金属有机框架(MOF)”材料方面的开创性工作。什么是“金属有机框架”?它对我们的生活会有什么改变。来听听该奖项得主之一的奥马尔·亚吉如何解释。

I'm Omar Yaghi, Professor of Chemistry at the University of California, Berkeley.

And, also, a Senior Staff Scientist at Lawrence Berkeley National Lab.

I'm also the Director of the Global Science Institute at Berkeley.

25 years ago we discovered materials we call now metal organic frameworks, or as they are now commonly called,MOFs.

These are composed of inorganic components, which you can think of them as metal-based, also, organic components that are carbon-based.

We can combine these together almost like molecular tinker toys.

We can combine them together by stitching them together into framework structures.

And these structures have pores, so on a minute level, or on the atomic nano level, if you hold a granule of a MOF you will see that that granule is riddled with holes.

In one gram of a MOF you have a surface area of 10,000 meters squared.

And all that space is stored within that small one gram material.
