摘要
近年来纳米尺度的贵金属材料由于其优良的催化性能、电学性能、磁学性能和光学性能等受到人们的广泛关注．不同形态和结构如颗粒状、线状、棒状、片状、不规则状的金属纳米粒子被相继合成。树枝状纳米银因其特殊的结构和潜在用途而得到大量研究，
Nanostructured silver dendrites were synthesized by using Sonochemical method from an aqueous solution of AgNO3 in the presence of isopropanol as reducing agent and polyethylene glycol （PEG） as disperser. The silver nanostructures were characterized by using TEM, XRD and EDS analysis. The effects of reducing agents, dispersers, concentration of AgNO3 on the silver dendrites nanostructures were also invetigated. A welldefined nanostructured silver dendrite was prepared by ultrsonic irradiation of the aqueous solution of 0.04 mol · L^-1 silver nitrate, 4.00 mol·L^-1 isopropanol and 0.04 tool·L^-1 PEG400 for 1 h.
