Investigation of specific state of molecules and ions formed inside one-dimensional micropore of single-walled carbon nanotube

Abstract

The aim of this thesis is to clarify the adsorption state of molecules or ions inside micropore of single-walled carbon nanotube (SWCNT). Firstly, we investigated that hydration structure around a zinc ion confined in micropore of activated carbons and SWCNTs by X-ray absorption fine structure (XAFS) technique and clarified the dehydration structure is formed around a zinc ion in less than 1 nm micropore of SWCNT and activated carbon. Next, we succeeded in analyzing for adsorption states of nitrogen, water and the hydration structure of zinc ion confined only in the inner pore of SWCNT by controlling the end-cap structure of SWCNTs without any changes in the surface states. Finally, we examined the adsorption phenomena and mechanism of bromide ion inside micropore of microporous carbons.
