Understanding Catalytic Converters

Catalytic converters are devices built into vehicles to reduce harmful emissions from the exhaust. They work by converting harmful pollutants such as carbon monoxide, nitrogen oxides and hydrocarbons into less harmful gases. Three main components found within the converter are the substrate, the washcoat and the catalyst.

The catalysts, generally made of precious metals such as platinum, palladium, and rhodium, are the key component in facilitating the chemical reactions necessary to reduce harmful emissions. Rhodium, in particular, is important in catalytic converters because of its unique ability to control and reduce nitrogen oxide emissions.

Extraction of the precious metals found within catalytic converters, like rhodium, has become increasingly popular as their value continues to rise.
