This infographic, "MOFs: What are they good for?", defines Metal-Organic Frameworks as crystalline "molecular sponges" made of metal ions and organic linkers. It details four commercial applications: carbon capture using zinc-based CALF-20, safer gas storage for semiconductor manufacturing, harvesting atmospheric water in deserts using aluminum-based MOF-303, and the detoxification of chemical warfare agents. It notes that MOF research won the 2025 Nobel Prize in Chemistry.
