Abstract

C60 molecules encased in single-wall carbon nanotubes, so-called peapods, can be transformed into small-diameter tubes inside the host tubes after high-temperature heat treatment in vacuum at ∼1200 °C. Here, we report an experiment on high-temperature heat treatment of peapods in inert gas environment, and show the evidence of enhancing the formation rate of inner tubes, the rate being more than ∼6 times higher in Ar environment and ∼9 times higher in He than that in vacuum. This means that the inert gas atoms markedly accelerate the polymerization of C60. In contrast to Ar and He, it is found that H2 gas does not enhance the C60 polymerization.
