A facile thermolysis route for the synthesis of amorphous carbon nanotubes (ACNTs) with bamboo-like morphology is presented, in which tetraethoxysilane is employed as carbon precursor. SEM and TEM results show that the obtained ACNTs exhibit a compartmentalized bamboo-like structure with an average outer diameter of about 30～40 nm and inner diameter of about 8～15 nm and several micrometers in length. The free of metal catalysts yields ACNTs, which is important for some fundamental scientific studies and also for promising applications.
