摘要：

Laser pyrolysis of hydrocarbons leads to soots containing different carbon nanostructures. The investigations of carbon nanopowders revealed the presence of the amorphous carbon, carbon with small graphitic sheets or fullerene-like structures. The soot morphology depends on the gas mixture and experimental parameters. The role of oxygen is essential in obtaining soot particles having considerable curved-layer content.
