A new synthesis method of nanomaterials using pulsed plasma in liquid by the low voltage spark discharge is presented. The fullerene C 60 and TiO nanopowder were for the first time synthesized by electric discharge method in liquid. The purity of C 60 was >99%, which is much higher than those by the conventional arc plasma in inert gas methods (less than 80% C 60 and 20% C 70 and other fullerenes). Copper nanoparticles prepared by this method were smaller than those by arc method by a factor of >5. The pulsed plasma in liquid enables us to quench from plasma state, by which we can synthesize nanomaterials, metastable materials, etc. In addition, the applied power is 100 times smaller than those of arc discharge.
