<正>Carbon nanotubes(CNTs) distinguish themselves from other carbon materials such as activated carbon and carbon nanofibers because they have a well-defined tubular structure formed by graphene layers.A number of substances have been introduced inside CNT channels such as fullerene and its derivatives,transition metal and metal oxides.The resulting nanostructured composite materials are often found to exhibit properties differing from both parent materials.Our previous studies showed that the redox properties of iron and iron oxide nanoparticles are modified when they are confined inside the CNT channels.
