Noble metal catalysts for monolithic converters


Catalytic combustion of pollutants released from the vehicular exhaust is one of the best methods to decrease their concentration before their release to the atmosphere. The catalyst help to bring about the reduction of these pollutants at a much lower temperature as compared to homogenous combustion reactions. In this paper a review about the noble metal catalysts used for gasoline vehicles is carried out. These noble metal catalysts although expensive and limited in supply are the best option for reduction of the pollutants hydrocarbons, carbon monoxide and oxides of nitrogen released from the vehicular exhaust.
