| Outline of Final Research Achievements |
To develop the systematic way to control the crystal structure of metal nanoparticles, we observe the formation process of Ru nanoparticles by in-situ experiments and synthesized novel monometallic and alloy nanoparticles. It was indicated that the structure of crystal nuclei in the formation process was important, and we found that the effect of metal precursors and the fine tuning of the reduction speed of different metal ions allowed us to control the structure of crystal nuclei for monometallic and alloy nanoparticles, respectively. Furthermore, the crystal structure of metal nanoparticles have an effect on their catalytic properties and it was shown that the crystal structure control would promote the effective usage of elements.
