Synthesis and Characterization of Platinum Doped Multiwall Carbon Nanotube,

Abstract

Carbon nanotubes (CNTs) were synthesised by catalytic chemical vapour deposition (CCVD) method. The synthesised CNTs was purified by acid (H2SO4 and HNO3) treatment to improve metal deposition on to CNTs surface. Platinum multiwall (Pt-MWCNTs) nanocomposites were then produced by wet impregnation of the platinum onto the surface of the MWCNTs. Surface morphology, chemical composition and crystallographic structure of the obtained Pt-MWCNTs nanocomposites were confirmed by Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), Energy Dispersive X-ray spectroscopy (EDS), X-ray Diffraction (XRD) and Brunauer-Emmett-Teller (BET).
