The core components responsible for a catalytic converter’s inherent worth are platinum, palladium, and rhodium. These are precious metals strategically employed within the converter’s structure to facilitate chemical reactions that reduce harmful emissions from internal combustion engines. These reactions convert pollutants like carbon monoxide, hydrocarbons, and nitrogen oxides into less harmful substances, such as carbon dioxide, water, and nitrogen.
The significance stems from both environmental regulations and material scarcity. Stringent emission standards worldwide mandate the use of catalytic converters in vehicles to mitigate air pollution. Furthermore, the limited availability and complex extraction processes of platinum group metals (PGMs) contribute to their high market value. This combination of demand and limited supply ensures a consistently high price for these materials, making the converters a target for theft and recycling.
