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.
