In a year that has already battered manufacturing supply chains, yet another shortage is complicating manufacturers’ and consumers’ lives: plastics, and the food packaging, automotive components, clothing, medical and lab equipment and countless other items that rely on them. But a new chemical catalyst developed at the University of Michigan could enable the production of more of the feedstock for the world’s second-most widely used plastic. The feedstock, propylene, is used to make the plastic polypropylene 8 million tons of it each year.

It is made of platinum and tin nanoparticles that are supported by a framework of silica.
