The use of platinum-group metals (pgm) in autocatalyst since the introduction of strict emission standards in the 1970s is reviewed and an assessment made as to whether supplies of pgm will be adequate to satisfy demand in the future.The principal factors that affect autocatalyst design are: severity of emissions legislation; details of test cycles used to measure emissions; nature of the fuel used in the engine; engine design; and catalyst technology. Developments in these factors, and their influence on the use of pgm in autocatalyst, are discussed.Finally, three aspects of pgm supply are addressed. World reserves of pgm are reviewed; the significance of the relative ratios of platinum, palladium and rhodium is considered, especially with respect to the future availability of rhodium; and the determinants of pgm prices are discussed.
