How does a catalytic converter work in an Audi A2?

I've heard about catalytic converters but I don't understand how they work. Can anyone explain how this specific component works in the Audi A2?

A catalytic converter works by converting harmful pollutants such as carbon monoxide and hydrocarbons into less harmful substances like carbon dioxide and water. In an Audi A2, the catalytic converter is located in the exhaust system and contains a catalyst made of precious metals that help facilitate the conversion process.

The catalytic converter in an Audi A2 uses a process called redox, which involves a chemical reaction between pollutants and the catalyst to produce less harmful emissions. This component is essential for reducing air pollution and is required by law in many countries.
