Before catalytic converters were developed, waste gases made by a car engine blew straight down the exhaust tailpipe and into the atmosphere. The catalytic converter sits between the engine and the tailpipe, but it doesn't work like a simple filter: it changes the chemical composition of the exhaust gases by rearranging the atoms from which they're made:

Molecules of polluting gases are pumped from the engine past the honeycomb catalyst, made from platinum, palladium, or rhodium.The catalyst splits up the molecules into their atoms.The atoms then recombine into molecules of relatively harmless substances such as carbon dioxide, nitrogen, and water, which blow out safely through the exhaust.
