Abstract

A technique has been developed to grow carbon nanotubes by flowing acetylene over pre‐reduced LaCoO~3~ catalyst in a fluidized‐bed catalytic reactor. Carbon nanotubes were characterized by means of SEM and TEM. The pre‐reduced LaCoO~3~ catalyst was found to be effective in producing carbon nanotubes with even diameter. The effects of reduction temperature of LaCoO~3~ on the growth of carbon nanotubes were investigated. This process can easily be scaled up.
