To reduce different types of emissions. Catalytic converters use different precious metals to catalyze different chemical reactions. For example, rhodium is used to reduce nitrogen oxide (NOx) emissions, while platinum and palladium are used to oxidize unburned hydrocarbons (HC) and carbon monoxide (CO) emissions.
