Application of Multifunctional Catalysts in Singlewall Carbon Nanotube Synthesis

In the present paper a review has been presented on the properties and applications of some monometallic and bimetallic nanoparticles as catalysts in production of single-wall nanotubes. An emphasis has been made on cobalt monometallic and cobalt/nickel bimetallic nanocatalysts due to their extensive use and special behavior. The patterns of behavior of the latter have been investigated by EXAFS spectroscopy, SEM and TEM analysis. Finally, the properties of monometallic nanoparticles have been compared with those of bimetallic particles.
