A catalyst is a key ingredient for many chemical reactions. It facilitates a molecule to change into another molecule, without being changed itself, meaning it can be used multiple times. However, many catalysts are made of precious metals, making them expensive and potentially harmful to the environment. Now, researchers have designed a catalyst made of a much more abundant metal—iron—to facilitate an important chemical reaction: the olefin metathesis reaction. Their work was published recently in Nature Catalysis.
