Carbon nanomaterials have been prepared using a simple production method of pulsed arc discharge between pure graphite electrodes in liquid. High-resolution transmission electron microscopy observation revealed that two kinds of nanomaterials can be produced in liquid. One of them is powdery products floating on the water surface, and another one is bulky deposits sank down in the water bottom. Some of them have multi-walled carbon nanofibers. Mean diameter of the nanofibers was approximately 30 nm. Optical emission of C +(426.7nm), Hα(656.3nm), Hβ(486.1nm) , Hγ(434.0nm), C2 swan bands and CO(457.1nm) can be observed in the arc discharge by using photonic multichannel spectral analyzer. These results indicate that the carbon nanomaterials have been produced by pulsed arc discharge in liquid.
