摘要

The sintering of precious metal particles during the operation of automotive three-way catalysts is considered to reduce the catalytic activity that degrades the catalysts. In this study, we demonstrated that the adsorption properties of Pt particles on the ceria surface as well as sintering behavior of Pt on the defect and defect free ceria surfaces.
