Converting toxic pollutants of the vehicular exhaust gas into less toxic form by catalyzed redox reaction is the function of catalytic converters. Expensive metals like rhodium (reduction catalyst), palladium (oxidation catalyst) and platinum (oxidation/reduction catalyst) are used for the catalytic process. These convert the hydrocarbons to carbon dioxide and water. Also, carbon monoxide and nitric oxide are changed to nitrogen gas and carbon dioxide.
