What Role do PGMs Play in Environmental Catalysis?
PGMs are instrumental in environmental catalysis, particularly in automotive catalytic converters. These devices reduce harmful emissions from vehicle exhausts by converting toxic gases like carbon monoxide (CO), nitrogen oxides (NOx), and hydrocarbons into less harmful substances such as carbon dioxide (CO2) and nitrogen (N2). Platinum, palladium, and rhodium are the primary metals used in these converters.
