Synthesis of Carbon Nanotubes at Low Temperatures Using Single Heating Source of Catalyst and Reactor in the Floating Catalyst Chemical Vapor Depositi

The synthesis of carbon nanotubes at temperatures as low as 540 ° C. was demonstrated by floating catalytic chemical vapor deposition. The use of ferrocene as a catalyst precursor uses catalytic cracking of benzene. In this work, the technique for introducing catalyst particles into the reactor has been developed by using a single heat source for the catalyst and the reactor. In order to observe the temperature distribution inside the reaction apparatus, the on-site monitoring apparatus was attached to the CVD apparatus. Two types of CNTs (array intertwining) were synthesized with a diameter distribution ranging from 10 to 40 nm.

Techniques for developing carbon nanotubes include arc discharge, laser ablation, chemical vapor deposition, and n-hexane pyrolysis. In order to produce carbon nanotubes, essentially three elements of carbon, heat and catalyst are essential. The process of producing carbon nanotubes is very complicated and expensive. These factors are presumed to limit the growth of the nanotube market during the forecast period. The world's nanotube market can be geographically separated into Europe, North America, Asia Pacific and other regions (lines). In the current situation, North America and Europe dominate the worldwide carbon nanotube market in terms of revenue. North America's major economies to promote market growth are the United States and Canada. Europe and North America are economic powers and invest in research and technology. The main European countries are the UK, Germany, France, Italy and Spain.

The concept of nanotechnology plays an important role in this process. The most basic method of forming carbon nanotubes is to inject a carbon-rich gas onto a planar catalyst under very high heat and pressure. Recent developments have enabled scientists to control the formation of carbon tubes and align them. The shaped material is pulled by a single tube and the other tube sticks to it during this process and forms the same structure as the line that is later woven into a strong fiber.
