Abstract

We clarified the adsorption sites inside the single-wall carbon nanohorns (SWNHs), a type of single-wall carbon nanotubes having thick diameters of 2-5 nm, through the thermogravimetric analysis of the desorption of xylene and benzene from SWNHs. The influence of the sizes of holes piercing through the SWNH walls was also examined. Three types of adsorption sites were found inside the SWNH tubes, which were assigned to the tube tips, the sidewalls, and central regions of the hollow spaces. The experimental results also suggested that the adsorbed xylene and benzene were stabilized mainly by weak self-interactions at the central regions and their quick desorption was caused by the weak self-interactions.
