Durability of Iron–Cerium–Carbon Catalyst on Electrical Heating Alumite Plate

Abstract

As an alternative for noble metals such as platinum that are included in three-way catalysts for exhaust purification in gasoline automobiles, an electrically heating alumite plate catalyst supporting iron–cerium–carbon was synthesized, and its properties in purification of automobile exhaust were examined. It was found that carbonization treatment at 800°C produced a Fe₃C phase in the catalyst. Catalysts treated by carbonization at 800°C for 2 h °C showed favorable purification of automobile exhaust and good durability, suggesting their potential for application as under-floor catalysts in automobiles.
