Hey kiddo, have you ever played with Legos? Metal-organic framework is like building with Legos, but instead of blocks, we use special molecules called organic compounds and metals.
Imagine you have a bunch of Legos with different shapes and colors, and you want to build a house. Similarly, scientists can use different organic compounds and metals to build a framework, which is like a tiny house or a cage.
These frameworks are full of tiny holes, like a sponge, that can trap and store gases such as carbon dioxide or hydrogen. They are also used to filter out impurities from liquids.
Metal-organic frameworks are very useful because they can be customized to have different sizes and properties depending on what they are being used for. They are also environmentally friendly because they can be reused many times.
So, just like building with Legos, scientists can build amazing structures that help save the planet!
