Abstract

A mass of amorphous carbon nanotubes (ACNTs) have been synthesized by chemical vapor deposition of C2H2 directly on Fe 76Si9B10P5 glassy alloy particles without the addition of an external catalyst at 550 °C for 1 h. The ACNTs is 1-5 μm in length and 5-30 nm in diameter and has a Brunauer-Emmett-Teller surface area of 81.4 m2/g. Investigations on the ACNT growth process confirmed that the initial stage for appearance of isolated islands (a-Fe nanoparticles), which might be due to stress and surface breakup generated during high temperature CVD process, would be the decisive step for the ACNT growth.
