碳纳米结构(洋葱、纳米管和包覆体)是在纯石墨电极和催化剂掺杂的石墨电极之间通过水中的弧光放电产生的。这些结构具有良好的质量和结晶形态，类似于在氦弧等离子体中形成的结构。用发射光谱分析血浆成分(H、O、C和C2)和温度值。根据石墨阳极组成的不同，在1015-1016 cm−-2之间定量地测定了C2自由基，温度在4000-6500K之间。
Carbon nanostructures (onions, nanotubes and encapsulates) were generated by arc discharge in water between pure and catalyst-doped graphite electrodes. These structures were of fine quality and crystalline morphology, similar to those formed in He arc plasma. Emission spectroscopy was performed to assess the plasma components (H, O, C and C2) and temperature values. C2radicals were determined quantitatively, between 1015and 1016cm−2depending on graphite anode composition.The temperature was between 4000 and 6500 K.
