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.

这里报道了一种独特的机械化学方法来产生复杂的纳米碳。已经证明，包括碳纳米管，碳洋葱和新的碳纳米的独特碳纳米结构是由钢球超高能球铣削合成的。据认为，气相反应发生在超高能量球铣削中碰撞能量引起的局部高温下，在钢球表面周围发生，这导致相分离出独特的纳米碳。这项研究还显示了金属氧化物纳米颗粒的机械化学合成，例如具有高温和高压相通过超高能量球铣削具有高温和高压相。
