Nano-technology is a super microscopic technology to deal with structures of 100 nanometers or smaller, and invovles developing materials or devices within that size. So far, electrochemistry method and photochemistry method generally have been used to make nano-size particles. However, the methods are complicated and make pollutants. In this study, nano-scale silver particles (5㎚) was prepared by sonochemistry method. TiO2 powders of 25 nm in size doped with Ag were formed by ultrasonic sound technique. The experimental results showed high possibility of removing pollution by playing a role of catalyst. This technique is a kind of environment-friendly powder forming processing because of energy saving method. |
