摘　　要：在90℃水浴条件下,以PVP为分散剂,用甲酸还原银氨溶液制备银纳米颗粒。紫外用-可见分光光度计检测银纳米粒子的生成过程,用X-射线衍射仪(XRD)和透射电子显微镜(TEM)对其结构和形貌进行表征,并用纳米粒度及Zeta电位分析仪测定其粒径分布。银纳米颗粒的粒径分布在60～70nm之间,而且粒子呈现球形结构。The silver ammonia solution was reduced to silver nanoparticles with the formic acid as the reductants and PVP as the protectants under water bath at 900 ℃. Uv spectrophotometer was used to test the generation of the silver nanoparticles. The structure and morphology were characterized by X-ray powder diffraction （XRD） and transmission electron microscopy （TEM）, the size distribution was determined by the Zetasizer NanoZS. The results show that the structure of the nanoparticles are spherical and the particle sizes distribute between 60nm and 70nm.
