Abstract

The present work is devoted to studying the products formed from C60 peapods after treatment at 8 GPa, from 200°C to 1200°C by SEM, TEM, XRD, and Raman techniques. It is confirmed that at temperatures up to 600°C the C60 molecules polymerize in forming the known 1D polymeric crystal with a C60 – C60 distance of 9 Å. In addition, we also find that at 1000°C the peapods begin to transform into different products including nanodiamond particles, amorphous carbon, and graphitic ribbons. At 1200°C only well-formed graphite is observed.
