Il n'existe qu'un petit nombre de catalyseurs capables d'effectuer dans des conditions optimales une réaction donnée. Le catalyseur réel adapté à un procédé particulier est le plus souvent un solide complexe. Il comporte une phase active qui, pour développer une surface maximale, est déposée sur un support, parfois à dose très faible s'il s'agit d'éléments coûteux comme les métaux précieux. Cependant, certains catalyseurs dits massiques sont uniquement constitués de phase(s) active(s) [...] [que l'on peut classer en trois grandes familles] : les métaux; les semi-conducteurs, oxydes, sulfures ou autres ions supportés; les oxydes isolants, acides ou basiques. 4, record 1, French, - catalyseur

L'épuration catalytique est un procédé [...] [qui] permet de réduire les émissions de CO, HC et NOX, sans modifier la carburation, en agissant directement sur les gaz d'échappement. C'est une technique relativement efficace tant que les catalyseurs que l'on emploie ne sont pas empoisonnés par le plomb (Pb), le soufre (S) et le phosphore (P). En effet, en présence de ces produits la longévité du système d'épuration est sérieusement réduite. 5, record 2, French, - convertisseur%20catalytique
