Single-walled carbon nanotubes (SWNTs) have been anticipated for applications to electronic devices because SWCNTs have superior electrical properties. In general, transition metals such as Fe, Co and Ni are widely used as catalysts for SWCNT growth. However, chemical states of catalyst metals during SWNT growth have not been clarified, although the reaction process is essential to control the structure of SWCNTs. In this study, we carried out in situ X-ray absorption near edge structure (XANES) measurements to clarify the chemical states of Fe catalysts during SWCNT growth.
