- Reasons for recommending:
There is great interest in the use of carbon nanotubes as templates for synthesis of other nanomaterials or as nanosized reaction vessels. Many studies have shown the benefits of using CNTs as a support for metal catalysts on the outer surface but few efforts have been made to carry out reactions on metals encapsulated within the nanotubes. Little is therefore known about the effects of confining chemical reactions in such a way. This paper reports the encapsulation of iron and iron-oxide particles within CNTs and investigates the interaction of the nanoparticles with the CNTs by Raman spectroscopy. The effect of these interactions on the reduction and oxidation reactions of the particles is investigated.
