CARBON NANOTUBE SYNTHESIS USING REFRACTORY METAL NANOPARTICLES AND MANUFACTURE OF REFRACTORY METAL NANOPARTICLES

摘要

Fabrication of refractory metal nanoparticles and carbon nanotubes is disclosed. As an example, a method may include providing a solvent and providing a surfactant having a first surfactant configured to stabilize low oxidation states of a refractory metal and a second surfactant configured to protect refractory metal nanoparticles. The method may further include providing a refractory metal precursor and providing a reactant for reacting with the refractory metal precursor and forming refractory metal nanoparticles. The refractory metal may include rhenium, tungsten, tantalum, or hafnium. The refractory metal nanoparticles may include rhenium, tungsten, tantalum, or hafnium nanoparticles. A carbon nanotube product may include refractory metal nanoparticles and carbon nanotubes, where the refractory metal nanoparticles may include rhenium, tungsten, tantalum, or hafnium nanoparticles.
