Catalytic converters are generally made from :

Options

A. Alkaline metals
B. Hydrogen
C. Transition metals
D. Carbon

Answer

C

Explanation

Transition metals are used directly as catalysis in the anti-pollution catalytic converters in car exhuastes, For example, expensive transition metals such as Platinum and rhodium are used in the catalytic converters in car exhaustes to reduce the emission of carbon monoxide and nitrgen monoxide, which are converted to the non-pollution gases nitrogens and carbon dioxide.
