Carbon nanotubes via different catalysts and the important factors that affect their production: A review on catalyst preferences

This review paper provides researchers with a comprehensive information about the carbon nano tubes and the catalyst parameters that influences the production and morphology of the of carbon nano tubes. carbon nano tubes, referred to as cnts, are one of the most important materials used in electrical, mechanical, thermal, chemical and textile industries. since the discovery of cnts in 1991, many scientists, research groups, and industries have attempted to attain large scale production of cnts, considering the costs and yields. catalyst plays an important role in the production of cnts. in this review various factors that affect cnt production via using different catalysts are reviewed. factors which are important when choosing a suitable catalyst are also discussed
