Both tungsten (W) and platinum (Pt) are materials of interest in modern science and technology. Here, in this paper, we report the growth of multi-walled carbon nanotubes (MWCNTs) by thermal chemical vapour deposition (CVD) on Pt-W catalyst with MgO as a support material. The XRD studies were used to determine the structural characteristic of the as-prepared catalyst. Raman spectroscopy studies confirm the growth of MWCNTs with less structural defects and non-crystalline carbonaceous products. The images of field scanning electron microscope (FESEM) show that the grown network of carbon nanotubes (CNTs) contains less impurities, whereas the high-resolution transmission electron microscope (HRTEM) images indicate that the grown MWCNTs have good crystallinity with no lateral carbon deposit. TGA of the unpurified CNT product shows the addition of catalyst particles with the sample. This study will pave way for the new research area in the synthesis of CNTs and their applications in the electronic industry. Moreover, the results were compared with the previously reported results in the literature.
