Arai, M. Kanamaru, T. Matsumura, Y. Hattori, S. Utsumi, T. Ohba, H. Tanaka, C. Yang, H. Kanoh, F. Okino, H. Touhara, K. Kaneko] Single wall carbon nanotube (SWCNT), which has bundle structure and entangled structure, was untangled and cut by sonication in hydrogen peroxide (H2O2) solution. The untangled state of SWCNT was examined by SEM, TEM, Raman spectroscopy and N2 adsorption. It was confirmed that the surface area of sonicated nanotubes strongly depended on the sonication time. The BET specific surface area (SSA) of nanotubes sonicated for 3h was maximum. The SSA decreased at 6h or more of sonication time. These results indicated that the bundle structure was untangled and the cap of SWCNT was opened. Thus, N2 molecules can access the most efficiently inside of the SWCNT sonicated for 3h. On the contrary, the sonication treatment for 6h or more decomposed the nanotubes to produce amorphous carbon, evidenced by TEM and SEM observation; the amorphous carbon blocked the open pore sites such as the internal pore spaces and interstitial pores.
