| Outline of Final Research Achievements |
Catalysts, which can convert molecules and energies to preferable forms, consist of nano particles and supporting substrates. To aim high-performance catalyst utilizing interaction between clusters (ultrafine particles) and substrates, catalytic activity and durability in CO oxidation and NO reduction proceeding on Pt clusters consisting of definite number of Pt atoms bound to CeO2, ZrO2 and Si substrates. The reactions on the Pt clusters on Si start at temperatures lower by several tens degrees with higher activity than Pt plates. The highest activity was observed for Pt clusters with 30 Pt atoms due to higher probability of O2 adsorption. The durability of the Pt clusters on the CeO2 and ZrO2 substrates is higher than the Si substrate.
