| Outline of Final Research Achievements |
Recently, extensive studies have been carried out on the syntheses and applications of polymetallic nanoparticles because they have unique electric, optical, magnetic, and catalytic properties which are absent in monometallic particles. In this study, we attempted to prepare new trimetallic nanoparticles for their catalytic applications. We succeeded in the preparation of Ag@PdAg@Ag nanorods and clarified their unique epitaxial growth mechanism involving alloying between intermediate Pd and outer Ag layers. Alloying between Pd and Ag layers were explained by ununiform distortion of Pd layers. We also succeeded in syntheses of AgPd@Pd/TiO2 catalysts for hydrogen production from decomposition of formic acid at room temperature and PtxY/carbon catalysts for oxygen reduction reaction in fuel cells. The latter catalysts are useful for the application to fuel cell vehicle in the near future.
