ABSTRACT

However, sulphur has been made use of as a promoter for carbon nanotubes (CNTs) synthesis for many years, a clear understanding of the sulphur effect (essentially, for efficient nanotube production) is still challenging. In this report, we intend to discuss the essential role of sulphur in an Aerosol–assisted chemical vapor deposition (CVD) CNTs synthesis. Though sulphur is not incorporated into the CNTs structure, its presence, however, indirectly affects the yield, nanotube thickness, and even defines a transition between single–, double–, and multi–walled CNTs. Scanning Electron Microscope (SEM), Transmission Electron Microscopy (TEM), and Raman Spectroscopy analyses were carried out in order to investigate the complex role of sulphur in CNTs synthesis. The effect of sulphur addition as a promoter on the growth of CNTs and attempted to provide insights into the role of sulphur during CNTs formation via catalyst characterization has been investigated

Keywords: Carbon nanotubes (CNTs), Sulphur, SEM, TEM, Raman Spectroscopy.
