A fluidized-bed reactor is employed to prepare carbon nanotubes. The carbon nanotubes are characterized by means of SEM and TEM. Using LaCoO3 as catalyst precursor and C2H2 as raw material, We study the influences of various parameters such as reduction temperature, reduction time, reaction temperature and reaction time on the yield and morphology of the nanotubes. The results indicate that the optimum conditions are: reduction temperature of 650 degreesC and reaction temperature of 675 degreesC.
