Summary

In this chapter, the vapor phase method is used to prepare tin oxide (SnO₂)-functionalized multi-wailed carbon nanotubes (MWNTs). SnO₂ nanoparticles are uniformly decorated on the outer surface of MWNTs. At the same time, parts of the MWNTs can be filled with SnO₂ nanoparticles. This simple technique is of interest for a distinct reacting process and efficiency. N,N-dimethyllformamide (DMF) had proved to be a good solvent in the process. The chapter presents an alternative route for the preparation of assembly of SnO₂ nanocrystals and carbon nanotubes. UV absorption indicates that the composite exhibits an obvious blue shift relative to that of pure SnO₂. Because SnO₂ has been uniformly anchored on the MWNTs and parts of the MWNTs were filled with SnO₂, this composite has potential application as a gas sensor used under ambient conditions.
