Abstract
In order to improve TWC performance it is essential to prohibit the deactivation of PGM particles on catalyst. In this study we investigated the influence of air to fuel ratio (A/F) in engine-exhaust aging on TWC performance and deactivation property of Rh catalyst. The catalyst reduced at high temperature exhibited the improved thermal durability and superior TWC performance. XAFS spectroscopy indicated existence of the small diameter or the disordered structure of Rh metal particles on the catalyst reduced at high temperature.
