The catalyst used in catalytic converters is finely divided ans. Pt Fe Ni Pd

The catalyst used in catalytic converters is finely divided Platinum (Pt) and Palladium (Pd). These precious metals facilitate the conversion of harmful gases into less harmful substances. Platinum is used to reduce nitrogen oxides to nitrogen and oxygen, while Palladium helps oxidize carbon monoxide to carbon dioxide and hydrocarbons to water and carbon dioxide.
