摘要

Characterization of iron containing alumina supported catalysts was performed by TEM, Mossbauer and XPS spectroscopy during formation of multiwall carbon nanotubes from acetylene at 1000 K. TEM images showed that carbon fibers (outer diameter is around 20-40 nm) were generated on Fe/Al_2O_3 samples while on the bimetallic Fe,Co/Al_2O_3 carbon nanotubes with an average diameter of 8-12 nm were formed. XPS spectra revealed that Fe-Co alloy formed during the interaction of Fe,Co/Al_2O_3 and acetylene at 1000 K. The formation of the bimetallic alloy was proven by Mossbauer spectroscopy as well.
