Catalytic convertors based on the use of platinum, palladium and rhodium play a major role in the cleaning of automobile emissions. Gold, when dispersed as nano-sized particles, has demonstrated significant activity in the conversion of toxic components, including carbon monoxide, unburnt hydrocarbons and nitrogen oxides, in engine emissions and so...

Le platine (Pt), le palladium (Pd) et le rhodium (Rh), font partie des Eléments du Groupe du Platine (EGP), utilisés dans les catalyseurs automobiles. En raison de leur émission dans l'environnement, ces éléments peuvent aujourd'hui être considérés comme des contaminants émergeants et traceurs de la contamination automobile. Cette étude porte sur l...

Environmental pollution (Barking, Essex : 1987)
Platinum-Group Elements (PGEs, i.e. platinum; Pt, palladium; Pd and rhodium; Rh) are extensively employed in the production of automotive catalytic converters to catalyze and control harmful emissions from exhaust fumes. But catalytic converters wear out over time and the emission of PGEs along with the exhaust fumes are nowadays known to be the ma...

Platinum group elements (PGEs, i.e. platinum, Pt; palladium, Pd; and rhodium, Rh) catalyse over 90% of carbon monoxide, nitrogen oxides and hydrocarbons from combustion residues into water vapour, carbon dioxide and nitrogen in the vehicle's catalytic converter. But there is a major concern over these metals in the scientific world, since they are ...
