From catalysts to quantum materials: exploring the future of platinum group metals

In an episode of the Physics World Weekly podcast, journalist Marge Ryan discussed the scientific and technological applications of platinum group metals (PGMs) with Johnson Matthey. The metals - platinum, palladium, ruthenium, rhodium, osmium and iridium - are rare and expensive materials with a variety of uses. Ryan, a chemical engineer with over 25 years of experience, explained how PGMs play crucial roles in the manufacture of pharmaceuticals and in catalytic converters that reduce harmful vehicle emissions.

These metals' high melting points and corrosion resistance make them useful in jet engines and glass production.

Beyond traditional uses, Ryan explored innovative applications such as plasmonics, quantum materials and spintronics. She noted that with the shift away from internal combustion engines, some PGMs may be freed up for new purposes. To foster research, Johnson Matthey and its mining partners established the PGM Award Scheme, providing materials free of charge to selected researchers.

Ryan also emphasized career opportunities for physicists in the PGM sector, including fundamental materials science, R&D, and commercial roles. For more information, Ryan can be contacted via a link provided in the podcast.
