Pretreatment of carbon nanotubes and its application in catalytic materials

Methods of synthesis of big inner diameter-carbon nanotubes and the effects of different pretreatments of carbon nanotubes on its performance have been reviewed.At the same time,the influence of preparation conditions on the activity of carbon nanotubes-based materials and carbon nanotubes-supported catalyst has also been introduced in this paper.The aim of this article is to deliver the information of putting catalyst into the inner cavity of carbon nanotubes.
