Simple and economical technique was used for synthesis of carbon
nanomaterials without using vacuum equipment. The used technique implied an
arc discharge between two pure graphite rods with different diameters submerged
in deionized water at room temperature. These were also investigated with a new
type of metal catalyst process for the first time. Plasma arc discharge was
produced using D.C power supply with current (30-90 amp.) and voltage (30-
50volt). The nanomaterials were produced in the form of nanoparticles (floated),
nanotubes and nanofibers (sank), and carbon nanocolloidal (dispersed) through the
water. The results of these experiments were examined by high resolution optical
microscope, scanning electron microscope SEM and transmission electron
microscope TEM. The results revealed different types of carbon nanomaterials.
