Answer: The correct answer is sodium

Catalytic converter-It used to reduce the emissions from an internal combustion engine.
The harmful fumes are converted into less harmful gases.
The catalytic converter is composed of a metal and has a ceramic honeycomb-like interior with insulating layers and thin wall channels.
As the coating is porous, the surface area is increased. Hence more reaction takes place.
Metals mostly used are Platinum, rhodium, and palladium.
Please note that only 4-9 grams of these precious metals are used in a single converter.
