摘要

A technique has been developed to grow carbon nanotubes by flowing acetylene over pre-reduced LaCoO3 catalyst in a fluidized- bed catalytic reactor. Carbon nanotubes were characterized by means of SEM and TEM. The pre-reduced LaCoO3catalyst was found to be effective in producing carbon nanotubes with even diameter. The effects of reduction temperature of LaCoO3 on the growth of carbon nanotubes were investigated. This process can easily be scaled up.
