A novel rapid mass production process of gold nanoparticles by using spark discharge in solution is proposed in this study. Into AuCl4 - aqueous solution, gelatin was introduced as the stabilizing reagent. Then, spark discharge at ca. 800 V was applied. The yellow solution turned into dark-red, which suggests the formation of gold nanoparticles protected by gelatin. UV-Vis spectra of the obtained dispersions indicates the complete reduction of Au3+ ions and production of gold nanoparticles. The TEM images revealed that gold nanoparticles were dispersed independently without aggregation. This process is quite unique and easy for mass production of various kinds of metal nanoparticles.
