Abstract

We created holes in single-wall carbon nanohorns (SWCNH) by oxidation (SWCNHox) and investigated how the hole size affected the incorporation of C₆₀ in SWCNHox and their release from it. The incorporation of C₆₀ inside SWCNHox first occurred when the holes were opened by oxidation at 475 °C. It was followed by a steep increase in the incorporation quantity with increasing oxidation temperature. The release rate of C₆₀ from inside SWCNHox was slower than that of C₆₀ crystallites located outside, and did not depend on the oxidation temperature (475-550 °C), indicating that the release rates were not influenced by the hole sizes.
