| Outline of Final Research Achievements |
Metallic nanoparticles such as gold nanoparticles and silver nanoparticles can be formed in liquid by irradiating a chloroauric acid aqueous solution or a silver nitrate solution with a nonequilibrium plasma. In this research, we focused on the use of mist in plasma from the viewpoint of reaction efficiency at the gas - liquid interface and control of particle size. We studied the method for the generation of mist-containing plasma, and developed a discharge reactor using ultrasonic atomization method and dc glow discharge, and a discharge reactor using electrostatic atomization method and corona discharge, and evaluated their characteristics. We also attempted to synthesize gold nanoparticles and silver nanoparticles using mist-containing plasma and confirmed its feasibility.
