The catalytic converter is made with trace amounts of platinum, palladium and rhodium, which speed chemical reactions and help clean emissions at very high temperatures. Selling stolen converters to scrap yards or recyclers, a thief can net a couple of hundred dollars apiece.
Did you know? Catalytic converters can effectively remove hydrocarbons, carbon monoxide, and nitrous oxides from car exhaust. But they do not reduce harmful emissions of carbon dioxide (CO 2), which is a greenhouse gas that contributes significantly to global warming.However, catalytic converters are less efficient when used with diesel engines, which run colder than gasoline engines. Catalytic converters work best at higher temperatures.his is accomplished using a catalyst, which gives the device its name. The catalyst used in a catalytic converter is a combination of platinum (Pt), palladium (Pd), and rhodium (Rh). These metals coat a ceramic honeycomb (or ceramic beads) contained within a metal casing that is attached to the exhaust pipe.
