Researchers capture speedy chemical reaction in mid-stride

In synthetic chemistry, making the best possible use of the needed ingredients is key to optimizing high-quality production at the lowest possible cost. The element rhodium is a powerful catalyst -- a driver of chemical reactions -- but is also one of the rarest and most expensive. In addition to its common use in vehicle catalytic converters, rhodium is also used in combination with other metals to efficiently drive a wide range of useful chemical reactions.
