How Do Catalysts Contribute to Meeting These Standards?
Catalysts play a crucial role in meeting Tier 3 emission standards by facilitating the chemical reactions that convert harmful pollutants into less harmful substances. Catalytic converters, a common application of catalysis in vehicles, use precious metals like platinum, palladium, and rhodium to accelerate the reduction and oxidation reactions that reduce emissions of NOx, CO, and hydrocarbons (HC).
