Preparation of Carbon Allotropes Using Different Methods

Carbon-containing substances have long been employed as sources of energy, and carbon is crucial to contemporary industry. Consequently, understanding carbon allotropes are essential for creating novel materials. Due to their distinctive characteristics, which make them ideal for a wide range of prospective uses, carbon nanotubes (CNTs) have been the subject of scientific study for more than fifteen years. The fields of nanoscience and nanotechnology continue to advance their research in order to create CNTs with adequate characteristics for applications in the future. Recently, a new type of nanocarbon material known as carbon quantum dots (CQDs) has attracted a lot of attention, particularly in solar cells, bioimaging, electrocatalysis, nanomedicine, and chemical sensors, as well as light-emitting diode (LED). The preparatory processes for CNTs and CQDs are the main topic of this chapter. The appropriate examples were used to discuss the complementary arc discharge, laser ablation, acid oxidation, and further carbon allotropes manufacturing processes. This chapter has also covered the benefits and downsides of each technique. New carbon allotropes might be created using the information in this chapter.
