【摘要】 以苯甲醇为介质,树枝状高分子PAMAM Dendrimers为稳定剂,硼氢化钾直接还原Ag(?)．形成高分散的纳米Ag颗粒;对比了加入和未加稳定剂对纳米Ag颗粒分散的影响;考察了水和苯甲醇中合成的纳米Ag颗粒的差异。通过透射电镜发现,苯甲醇介质合成的颗粒在铜网上形成了单层的高分散的纳米Ag颗粒．其直径为 5～10 nm。更多还原

【Abstract】 A simple route for the synthesis of Ag nanoparticles in benzyl alcohol was reported. Such nanoparticles could be fabricated by the reduction of KBH4 with the starburst dendrimers as capping agent in benzyl alcohol. The influence of the capping agent PAMAM dendrimers was investigated. On a carbon-coated copper grid, the nanoparticles synthesized in benzyl alcohol formed a monolayer film, which can be observed by TEM. and the diameter of Ag nanoparticles was in the range from 5 to 10 nm.更多还原
