New hybrid material based on multiwalled carbon nanotubes decorated with rhenium nanoparticles

The deposition of rhenium nanoparticles on the surface of multiwalled carbon nanotubes (MWCNTs) is conducted by metal organic chemical vapor deposition (MOCVD) technology. The synthesized hybrid materials are analyzed using scanning electron microscopy, high-resolution transmission electron microscopy and powder X-ray diffraction. The dependence of the sizes and shapes of the deposited rhenium nanoparticles on the initial synthesis parameters is established. It is found that the size distribution of rhenium nanoparticles is bimodal on the surface of MWCNTs.
