摘要：
A new strategy for the synthesis of carbon nanotubes without any catalyst via the reaction between difluorocarbene (CF2) radicals generated from a precursor (hexafluoropropylene oxide) and porous silicon nanowire arrays at low temperature is reported in this study. No further post treatment is needed and a high CNT purity of similar to 90% is achieved. A four-step formation mechanism is proposed to understand the growth process of the carbon nanotubes.
