P19 CTAB 水溶液中での貴金属ナノ粒子の超音波還元合成

Metal nanoparticles have been applied and researched in various fields (catalysts, sensors, cancer treatments). Although the particle size and shape of metal nanoparticles formed have been investigated in details, the number of reports on investigating the nucleation and growth processes of metal nanoparticles is still limited. In this study, we discussed the nucleation and growth processes of gold and palladium nanoparticles by using a standing wave sonication system with 200 kHz ultrasound. In addition, we tried to synthesize size- and shape- controlled gold and palladium nanoparticles as a function of various experimental parameters of organic and inorganic additives.
