Found this: https://investingnews.com/innspired/palladium-platinum-catalytic-converters-metals-market/
From that link:
Palladium has better thermal stability than platinum and can withstand the temperatures of gasoline exhaust. Palladium is more widely used in the catalytic converter market for gasoline-powered cars, while platinum is the go-to metal for the diesel-fueled vehicle market. Demand for diesel-powered vehicles has been shrinking, decreasing platinum demand from the catalytic converter market.
I haven't done any other searching so I don't know.
