The Development of the process to synthesize carbon nanotubes from biogas

Abstract

Carbon nanotubes are molecular-scale tubes of graphitic carbon with outstanding mechanical, electrical, chemical and thermal properties. This thesis explains a simple process has been developed to synthesize carbon nanotubes from biogas by the method of chemical vapor decomposition. In this process, Ni/SiO2 was used as catalyst at 5500C temperatures. The biogas was supplied to the reactor for one hour continuously. The final sample was investigated by means of scanning electron microscope (SEM). The role of catalysts particle, reaction temperature and reaction mechanisms of methane decomposition in front of carbon dioxide are also discussed. Further, the design, material selection, fabrication and modification of the reactor also discussed in this thesis.
