Abstract: Carbon is a chemical element with the symbol C atomic number newline6 and electron configuration He 2s2 2p2 Carbon is set as the sixth element newlineof the periodic table The hybridization of carbon consists of sp for example newlineC2H2 sp2 for example graphite or sp3 for example CH4 newlineCarbon nanotubes CNTs have a tubular structure made of carbon newlineAtoms with diameter of nanometer range and length in micrometers Since newlineIijima s landmark publication the CNTs are widely used in many newlineApplications The application of CNTs is typically governed by the CNTs newlinestructure number of walls diameter length chiral angle etc which assign newlinethem various properties newlineCNTs can be basically classified as single walled nanotubes newline SWNTs and multi walled nanotubes MWNTs CNTs also exist in different newlineshapes such as toroidal coiled and branched other than the straight All these newlinestructures depend on the introduction of non hexagonal defects in seamless newlinehexagonal networks The regular helical coils of CNT s are derived from a newlinevery definite packing of pentagons and heptagons in a perfect hexagonal newlinelattice Carbon nanotubes are generally produced by three main techniques newlinearc discharge laser ablation and chemical vapour deposition CVD newlineCompared with other techniques catalytic CVD is considered to be an newlineeconomically feasible process for large scale and pure CNTs production The newlinemain advantages of CVD comprise easy control of the reaction newline newline
