摘    要:采用化学还原法制备了纳米Ag粉,并通过X射线衍射(XRD)、透射电子显微镜(TEM)、红外吸收光谱(FT-IR)、热失重分析(TGA)和差示扫描量热分析(DSC)等测试手段对样品进行性能表征.结果表明:在所选择的实验条件下制备了类球形分布、分散性好的Ag纳米颗粒,其粒径主要分布在10~50nm范围,平均粒径为26nm,晶体结构与相应的块体材料基本相同,为fcc结构,具有很强的吸附性.

关 键 词:金属材料  银纳米粉  化学还原法  粒度  性质

Abstract:Silver nanopowders were synthesized by chemical reduction method at room temperature.The product was characterized by x-ray diffraction(XRD),transmission electron microscopy(TEM),FT-IR spectrum,thermogravimetric analysis(TGA)and differential scanning calorimetry(DSC).The experimental results showed that the Ag nanoparticles are in high dispersion state with uniformly quasi-spherical shapes,the average particle size is about 26nm with a narrow size distribution ranging from 10nm to 50nm.It is also found that the crystal structure of the Ag nanopowders is the same as the bulk materials,namely fcc structure and that the nanopowders have strong adsorption property.
Keywords:Metal materials  Sliver nanopowders  Chemical reduction method  Particle size  Property
