Title: Catalyst activity function and sintering behavior of Pd-based TWC
Sung Bong Kang, Postdoctoral Researcher, University of Houston
In this study, the 3-dimensional activity function for the Pd-based three-way catalysts (TWC) has been developed on the basis of the active metal surface area (MSA) over the wide range of Pd loadings and catalyst mileages to predict the TWC performance. Furthermore, the sintering kinetics of the Pd catalyst has been systematically investigated with a variety of initial Pd particle sizes and catalyst mileages to better understand the effect of the initial Pd particle size on the sintering behavior of the Pd TWC based on the Ostwald-ripening mechanism.
