Authors Abstract
Content
A newly developed three-way catalyst (TWC) has excellent thermal durability with an ultra low amount of platinum group metals (PGM). The performance of the new catalyst is similar to that of a conventional TWC but with only 1/10 of the typical PGM loading. In the conventional TWC, the PGM particles are simply deposited on the surface of the support material; the particles sinter during thermal aging, resulting in significant thermal deterioration. The new developed catalyst contains small nano-sized PGM particles with a unique microstructure and support materials. With this material, the PGM particles remain at the single nano size after high temperature aging.
