What is what metal is in a catalytic converter?

Catalytic converters typically contain a combination of several different metals, including platinum, palladium, and rhodium. These metals serve as catalysts, helping to convert harmful pollutants in vehicle exhaust gases into less harmful substances. Platinum is the most commonly used metal in catalytic converters, as it is effective at converting carbon monoxide and hydrocarbons into carbon dioxide and water. Palladium and rhodium are also used in smaller amounts to help reduce nitrogen oxides and other harmful emissions. These metals are valuable and can be recycled from old catalytic converters.
