Ionic liquids (IL) have attracted much attention for excellent characteristics and chemical reaction field of metal nanoparticle. The transition metal nanoparticles as catalyst progress to form nano carbon materials such as carbon nanotubes. The shape of this nanoparticles is possible to influence the properties of nanocarbon materials. On our previous work, we have observed that the behavior of the ionic liquid molecules and transition metal atoms may be different with each surface structure (Si-rich or C-rich) on transition metal deposited IL/SiC surface. We focused on Si-rich surfaces, the surface structure was observed to clarify the behavior of transition metal atoms on the IL covered Si surface after annealing and the formation process of nanoparticles. In this study, we will report the observation results of the surface structure when the amount of Pt deposited is varied up to 40 nm and the substrate annealing temperature is also varied.
