摘要
SiC/SiO2 nanocables were synthesized by pyrolysis of poly( dimethyl siloxane) using ferrocene as a catalyst precursor at similar to 1050 degrees C in Ar. The as-grown product was characterized by x-ray diffraction, scanning electron microscopy, transmission electron microscopy and high-resolution electron microscopy. The length of the nanocables is in the millimeter range and the diameter of most nanocables is in the range of about 5-10 nm. The vapor-liquid-solid (VLS) mechanism was proposed to elucidate the growth process of the nanocables.
