Abstract
A technique has been developed to grow carbon nanotubes by flowing acetylen e over pre-reduced LaCoO3 catalyst in a fluidized-bed catalytic reactor. Ca rbon nanotubes were characterized by means of SEM and TEM. The pre-reduced LaCoO3 catalyst was found to be effective in producing carbon nanotubes wit h even diameter. The effects of reduction temperature of LaCoO3 on the grow th of carbon nanotubes were investigated. This process can easily be scaled up.
