摘　　要：以AgNO3为原料,利用天然松香中的还原性物质枞酸还原银氨络离子得到银纳米颗粒,利用油酸等与纳米颗粒的相互作用在表面形成一层保护层来防止纳米颗粒的聚集。并用UV-vis、TEM和XRD对其进行检测和表征。通过控制反应条件,可制得粒度分布较均匀、结晶性能良好的银纳米颗粒。A novel route to synthesize crystalline silver nanoparticles is presented, which is based on reducing AgNO3 with C20H30O2 in nature rosin. The nature rosin is used as protecting and reducing agent in order to avoiding conglomeration of silver nanoparticles. The morphology and chemical composition of the silver products obtained were characterized by UV - Vis ,TEM and XRD. The ball silver nanoparticles, uniformity granularity crystals can be obtained by controlling reaction conditions.
