Abstract
The chapter presents and discusses the production of graphene sheets of carbon nanotubes (CNT) of various types. The Iijima arc discharge method, following the purification methods, is described identifying advantages and disadvantages. Several types of non-regularities such as the Stone–Wales defect and corner effect, which locally increases reactivity, are described from the structural point of view. The laser ablation method is presented as one of the most prominent methods in the production of CNTs. The catalytic chemical vapour deposition (CVD) method is a very effective tool for the controlled production of different carbon shells. The sporadic and simulated growth of CNTs depends on thermodynamic conditions (temperature, vapour pressure) as well as on the surface properties (size and the type of catalyst particles). The chapter also presents the model of magnetically stimulated CNT growth for a special case of Fe–Pt metallic nanoparticles, which have unique magnetic properties. We expect that in the presence of a magnetic field the growth of CNTs will be more determined from the point of view of possible CNT morphologies.
