Apstrakt

Da bi se smanjilo zagađenje vazduha i ispoštovala zakonska regulative, u izduvne sisteme motornih vozila (putnička, teretna i druga vozila, a u poslednje vreme i građevinske i poljoprivredne mašine) ugrađuju se katalizatori tj. katalitički konvertori. Njihov zadatak je da štetne proizvode sagorevanja tečnih fosilnih goriva prevedu u manje štetne produkte. U katalitičkim konvertorima, rodijum se koristi za redukciju, a platina i paladijum za oksidaciju gasova. U radu su prikazani struktura i princip rada auto katalizatora budući da su automobili najzastupljenija motorna vozila na putevima širom sveta i da se predviđa da će bar do 2020. godine dominirati proizvodnja automobila sa benzinskim i dizel motorima.
