Structure of the C₆₀ nanowhiskers (C₆₀NWs) heat-treated at high temperatures was investigated by high-resolution transmission electron microscopy (HRTEM), electron energy loss spectroscopy (EELS), Raman spectrometry, thermogravimetric analysis, Brunauer-Emmett-Teller (BET) method, and so forth. Although the C₆₀NWs heated at 800 °C in vacuum showed a remaining of C₆₀ molecules, the C₆₀NWs became amorphous by heating at 900 °C in vacuum, exhibiting the highest specific surface area of 195.2 m²g^-1.The porous nanofibers synthesized by heating C₆₀NWsat high temperatures are new candidates of superconductive graphitic carbon.
