Synthesis of carbon nanostructures using the chemical vapor deposi-tion technique: An overview

Abstract

The boom in nanotechnology over the last three decades is undeniable. Responsible for this interest in nanomaterials are mainly the nanostructured forms of carbon, since historically they were the ones that inaugurated the study of nanomaterials with the discovery of fullerenes in 1985 and carbon nanotubes in 1991. Although a variety of techniques exist to produce these materials, chemical vapor deposition (CVD) is particularly valuable as it allows the production of a wide variety of carbon nanostructures, is versatile, scalable, easy to implement and relatively low cost. This review article highlights the importance of CVD and details its principles, operating conditions and parameters, as well as its main variants. A description of the technique used to produce fullerenes, nano-ceramics, carbon nanotubes, nanospheres, graphene and others is made, emphasizing the specific parameters for each synthesis.

Fabrication of tunable band gap carbon based zinc nanocomposites for enhanced capacitive behaviour

“…Carbon nanospheres are formed as a result of the pairing of pentagonal and heptagonal carbon rings which form circular concentric graphite layers and are called carbon nanospheres. They can be synthesized by a variety of methods including chemical deposition method (CVD), hydrothermal method and by usage of hydrocarbons and biomass [11][12][13][14][15][16][17][18]. They can be used in a variety of applications viz.…”
