Catalytic converters in automobiles use metal catalysts (e.g., platinum, palladium, rhodium) to convert harmful exhaust gases (CO, NOx, and hydrocarbons) into less harmful products (CO2, N2, H2O). The metals facilitate redox reactions on their surfaces, reducing emissions and meeting environmental regulations. Proper catalyst design and maintenance are crucial for vehicle performance and pollution control.
