Question

Catalytic converters having expensive metals as catalysts have

• A. Silver-Palladium and Strontium
• B. Platinum-Silver and Palladium
• C. Platinum-Palladium and rhodium
• D. Silver-Palladium and Strontium

Answer 1

The correct option is C Platinum-Palladium and rhodium

A catalytic converter is a device that uses redox reaction mechanisms to convert toxic substances present in emissions into less toxic ones. The catalyst in such converters is made from platinum or a similar, platinum-like metal such as palladium or rhodium.

So, the correct option is 'Platinum-Palladium and rhodium'.
