| Research Abstract |
Herein a unique mechanochemical approach to produce sophisticated nanocarbons is reported. It is demonstrated that unique carbon nanostructures, including carbon nanotubes, carbon onions, and new carbon nanorings are synthesized by super-high-energy ball milling of steel balls. It is considered that the gas-phase reaction takes place around the surface of steel balls under local high temperatures induced by the collision energy in super-high-energy ball milling, which results in phase separated unique nanocarbons. This study also shows the mechanochemical synthesis of metal oxide nanoparticles such as ilmenite with a high-temperature and high-pressure phase by the super-high-energy ball milling.
