摘　　要：在Ag(NH3)2+溶液中,采用电沉积法制备出不同形貌的纳米银颗粒,研究了基底、电解质溶液温度和沉积电位对纳米银颗粒形貌的影响。结果表明,在以钛为基底,电解质温度为20℃,沉积电位位-1.6 V(vs Ag)的条件下,制备的纳米银颗粒(Ag/Ti)呈形状较为规整的树枝状。Ag nanoparticles with different dentrite-like structures were prepared by using the electro-deposition process in Ag（NH3）2＋ solution.The effecting of substrate,temperature and deposition potential on the morphology of Ag nanoparticles were studied.Results show that a well-difined dentrite-like structure of Ag nanoparticles on the Ti was obtained at 20 ℃ by using the deposition potential of 1.6 V.
