Single-walled carbon nanotubes (SWNTs) have been anticipated for applications to electronic devices because SWNTs have superior electrical characteristics. It is important to grow small-diameter SWNTs. So far, using Pt catalyst, we have succeeded in obtaining SWNTs with small diameters below 1.0 nm .In this study, we investigated chemical states of Pt catalysts during SWNT growth by X-ray absorption near edge structure (XANES).
