Metal-organic frameworks (MOFs) are materials made from metal ions or clusters linked by organic molecules. They have a porous structure, which allows them to store and separate gases, making them useful in various applications like gas storage, catalysis, and drug delivery. Due to their high surface area and tunable properties, MOFs can be designed for specific tasks. Researchers are exploring their potential in areas such as carbon capture, hydrogen storage, and sensing, highlighting their versatility and importance in addressing environmental and energy challenges.
