Synthesis of carbon nanotubes over In situ-reduced perovskite-type oxides

摘要

Carbon nanotubes (CNTs) of uniform size can be abundantly produced by the catalytic decomposition of CH_4 over metal (Fe, Cu) nano- particles prepared in situ by the reduction of perovskite-type oxides in a fluidized-bed catalytic reactor. The quality of CNTs obtained was characterized by means of transmission electron microscopy (TEM). The results revealed that CNTs with various structures could be obtained from different perovskite-type oxides.
