| Research Abstract |
The purpose of this study is to clarify the strategy for the long-life automobile catalyst having higher activity at low temperature, controlling the self-assembly of metal nanoparticles and nano clusters. The following results are obtained: (1) the self-dispersion of Ag, Ru, and Pd over CeO2 surface and its mechanism are clarified, (2) the key factors for the higher catalytic activity at low temperatures are reducibility of metals and oxygen storage and release properties of supports, (3) based on the result (2) we developed Pd/TiO2/CeO2 which shows the CO oxidation activity 100 oC lower than ordinary Pd/Al2O3 catalyst.
