A catalytic converter is a device in the exhaust pipe of a car, near its engine, to clean up the exhaust the car sends out into the air. It works by using a catalyst material, usually made of Platinum, Palladium, and Rhodium. The catalytic converter changes carbon monoxide, hydrocarbons, and nitrogen oxides, all of which make the air dirty and make people sick, into carbon dioxide, water, and Nitrogen, all of which are less harmless however are still the main reasons for global warming.
