Abstract:
The effect of cobalt, nickel, cobalt/nickel, cobalt/ferrocene, nickel/ferrocene and ferrocene catalysts on the morphology and yield of boron carbonitride(BCN) nanotubes produced by thermal decomposition at 860℃ was studied. It is found that the catalysts have a strong effect on the growth of BCN nanotubes. Transmission electron microscopy images reveal that bamboo-shaped thinner wall nanotubes with a higher yield are produced with nickel/ferrocene and cobalt/ferrocene as catalysts, whereas thicker wall nanotubes with a lower yield are generated with cobalt, nickel and cobalt/nickel as catalysts. BCN nanotubes cannot be produced with ferrocene alone as catalyst. Catalyst particles were found together with the BCN nanotubes. The morphology and yield of BCN nanotubes depend on the catalysts in the following order: nickel/ferrocene≈cobalt/ferrocene〉cobalt≈nickel〉cobalt/nickelferrocene. Their Raman spectroscopies were also studied.
