Decoration of Carbon Nanotubes with Metal Nanoparticles by Wet Chemical Method: A Small-Angle Neutron Scattering Study
Multi-wall carbon nanotubes have been synthesized by catalytic chemical vapour deposition method. Attempts have been made to decorate the walls of these nanotubes with various metal nano-particles (Ni, Cu and Fe) after functionalizing the nanotubes walls by wet chemical method. Small-Angle Neutron Scattering data reveals chain cluster type morphology of the carbon nanotubes. Transmission electron microscopy, Energy dispersive analysis of X-rays and Small-Angle Neutron Scattering measurements show that decoration of nanotube walls by metallic nano-particles could be realized for Ni and Cu nano-particles. Further, wall decoration by nano-particles of Fe could not be achieved by wet chemical method due to strong agglomeration behavior of Fe nano-particles.
