Single-walled carbon nanotubes (SWNTs) have been anticipated for applications to electronic devices because SWNTs have superior electrical characteristics. Using Pt catalyst, we have succeeded in obtaining SWNTs with small diameters below 1.0 nm. However, growth mechanism of SWNTs from Pt catalysts has been unclear. In this study, we investigated chemical states of Pt catalysts during SWNT growth by in-situ X-ray absorption near edge structure (XANES).
