Notes:
Nano-sized metal particles have recently attracted considerable interest owing to theirapplication potential. Such particles can be synthesized using physical and chemical methods. Inthis study, nano-sized noble metals were synthesized through the reaction of metal oxides byultrasonic. This means that the chemical reactions which take place under conventional conditionscan be accelerated by ultrasonic cavitations. In general, the chemical effects of ultrasonicirradiation fall into three areas: homogeneous sonochemical efffects of liquids, heterogeneoussonochemical effects of liquid-liquid or liquid-solid systems, and sonocatalytic effects. It has beenproposed that liquid-liquid systems are used for the fabrication of nano-metal particles in the past.In this study, the fabrication of nano-metal particles and supported composites was investigated forthe liquid-solid system from a viewpoint of economy and ecology. By choosing suitableconditions, it is reasonable to expect that these simple ultrasonic processes can be extended toobtain nano-sized metal particles. Thus applications by using these reactions were investigated toprepare the nano-sized metal particle supported materials, and mechanisms were investigated
