Are carbon nanotubes organic or inorganic?

Carbides (e.g., SiC) and CO/CO2 are considered inorganic compounds, for example. Diamond is not considered organic either. Carbon nanotubes, fullerene, graphene and graphene oxide are allotropes of carbon, such as diamond, and therefore are not considered organic either.

Does carbon nanotubes occur naturally?

Although it is generally assumed that carbon nanotubes are naturally occurring, there is surprisingly little evidence to support this assumption1. There has been enormous growth in patents related to carbon nanotubes, fuelled by predictions that the market for nanotubes will be $9 billion by 20204.

How is carbon nanotube produced?

Techniques have been developed to produce carbon nanotubes in sizable quantities, including arc discharge, laser ablation, high-pressure carbon monoxide disproportionation, and chemical vapor deposition (CVD). Most of these processes take place in a vacuum or with process gases.

Which method is used for the joining of carbon nanotubes?

A new method is called microwave plasma based functionalization. During the procedure of plasma based purification, some process gasses are directed into the plasma reactor . When triggered by the energetic plasma, it forms covalent bonds between the surface of the carbon nanotubes and the functional groups.

    • Where are carbon nanotubes used?

    As of 2013, carbon nanotube production exceeded several thousand tons per year, used for applications in energy storage, device modelling, automotive parts, boat hulls, sporting goods, water filters, thin-film electronics, coatings, actuators and electromagnetic shields.

    How are carbon nanotubes prepared describe any two methods?

    Commonly, three procedures are being used for producing CNTs: (1) the chemical vapor deposition (CVD) technique [12,13], (2) the laser-ablation technique [3,9], and (3) the carbon arc-discharge technique [14-16] (Table 3).
