RE:RE:RE:RE:Regenx’s New Year Communicationiscfa- Diesel catalytic converters do not usually contain rhodium. Instead, they contain platinum and palladium. There's usually no Rhodium in diesel auto-catalysts. This is because Rhodium is ineffective in reducing NOx in diesel exhaust due to its high oxygen content.

Also, "Diesel engines typically run much cooler than gas engines, so they need a different process to ensure that the toxic substances are successfully neutralized."
