Huczko, “Synthesis of Aligned Carbon Nanotubes,”

Synthesis:
Since these methods were developed substantial progress has beenmade (particularly in Japan where they have always been at the forefrontof nanotechnology) on improving the production techniques for carbon nanotubes,including increased production efficiency, higher purity and the developmentof new techniques.

Controllable synthesis of carbon nanotubes (CNTs) via autothermal reforming of ethyl acetate and waste cooking oil was studied for the first time. The products of the products were characterized by techniques of FESEM, XRD, HRTEM, Raman and XPS. Results revealed that reaction temperature, reaction time and reactants significantly affected the growth of CNTs. Ethyl acetate could be easily catalyzed into CNTs at 600 °C, which contained numerous defects and vacancies. High reaction temperatures led to the formation of CNTs with small diameter. The graphitization and purity of CNTs could be improved by increasing the reaction time. Besides, the amount of CNTs decreased by increasing the reaction time at low reaction temperature (2 and H2O in reactants reduced the formation of irregular carbon species and promoted the synthesis of CNTs with ultra-small diameter. Two growth mechanisms for synthesizing CNTs from ethyl acetate via autothermal reforming were proposed: “tip-growth” mechanism and “graphene-to-CNTs” mechanism. Furthermore, the real waste cooking oil was also successfully catalyzed into CNTs.

Rolling a carbon nanotube out of graphene.

i) the manufacture of synthesis gas (a mixture of carbon monoxide and hydrogen (steam reforming))

Also, it describes the rational design of graphene nanoribbons via intercalating reactive metals into multi-walled carbon nanotubes followed by addition of vinyl monomers or haloalkanes.

Carbon nanotube represent one of the best novel nanostructures which have different individual structures,morphologies and properties, a wide variety of synthetic methods have been developed to produce it and the properties for specific scientific studies or technological applications. Carbon Nanotube are one of the allotropes of carbon which can be described as a sheet of graphite rolled into a hollow cylinder constructed from hexagonal rings of carbon with diameters ranging from one to tens of nanometers, and with lengths up to micrometer.

A method is reported for detecting the hydrocarbon in the porous media with stabilized nanoparticles that are capable of efficiently transporting hydrophobic molecules through oil-containing rocks and selectively releasing them when a hydrocarbon is encountered.

Encapsulation of coronene inside single-walled carbon nanotubes (SWNTs).

Syngas has 50% of the energy density of natural gas. It cannot be burnt directly, but is used as a fuel source. The other use is as an intermediate to produce other chemicals. The production of syngas for use as a raw material in fuel production is accomplished by the gasification of coal or municipal waste. In these reactions, carbon combines with water or oxygen to give rise to carbon dioxide, carbon monoxide, and hydrogen. Syngas is used as an intermediate in the industrial synthesis of ammonia and fertilizer. During this process, methane (from natural gas) combines with water to generate carbon monoxide and hydrogen.

Syngas is an abbreviation for synthesis gas, which is a mixture comprising of carbon monoxide, carbon dioxide, and hydrogen. The syngas is produced by gasification of a carbon containing fuel to a gaseous product that has some heating value. Some of the examples of syngas production include gasification of coal emissions, waste emissions to energy gasification, and steam reforming of coke.
