Structure of inorganic nanocrystals confined within carbon nanotubes

Abstract

There are many examples in which the cavities of carbon nanotubes have been filled with a variety of compounds. Unprecedented structures compared to those of the same material in the bulk are observed, such as low dimensional crystals. Such encapsulated materials can have unusual properties that differ from those of the bulk material. The scope of this review is to give a brief approach to the different nanostructures formed after encapsulation of inorganic compounds within the inner cavities of carbon nanotubes. The confined materials can take the form of one-dimensional anowires, nanoclusters or even inorganic nanotubes.
