Metal-organic frameworks (MOFs) are materials made from metal ions linked by organic molecules, forming a porous structure. These frameworks can trap gases and liquids, making them useful for applications like gas storage, separation, and catalysis. Their high surface area and tunable properties allow for customization based on specific needs. MOFs are being researched for various uses, including carbon capture and drug delivery. Their unique structure enables them to selectively absorb certain molecules, which can improve efficiency in chemical processes. Scientists continue to explore new combinations of metals and organic linkers to enhance their performance and functionality.
