| Abstract: Silicon carbide nanotubes (SiCNTs) were prepared by chemical vapor deposition (CVD). Methyltrichlorosilane (MTS) was selected as the SiC gaseous source and, ferrocence and thiophene as the catalyst and the cocatalyst, respectively. The influences of pyrolysis temperature, the content of catalyst and the cocatalyst, and the mole ratio between H2 and MTS, on the shape of the pyrolysis products were investigated, respectively. The products were characterized by SEM, EDX, XRD and HRTEM, respectively. Novel type of multi-walled SiCNTs, with 30～80 nm and 15～20 nm outer and inner diameters, respectively, were observed. |
