Question

The chambers present in catalytic converters does not contain catalytic material, which promotes the oxidation of the emissions contained in the exhaust flow.

(a) True

(b) False

This question was posed to me in unit test.

My doubt stems from Catalytic Converters topic in portion Engine Emissions and their Control of IC Engine

Answer 1

The correct answer is:

(b) False

The chambers in catalytic converters do contain catalytic materials, such as platinum, palladium, and rhodium. These materials promote the oxidation and reduction reactions that convert harmful emissions in the exhaust gases into less harmful substances. The catalysts lower the activation energy needed for these chemical reactions to occur, which helps reduce pollutants like carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx).
