摘要
以阳离子交换树脂为模板制备了单质银空心微球,采用扫描电镜（SEM）、X射线能量散射谱（EDS）、X射线衍射谱（XRD）、X射线光电子能谱（XPS）、紫外-可见光谱（UV-Vis）等手段对其进行了表征。结果表明：所制备的单质银微球呈表面多孔的空心结构,直径在200～500μm之间,微球表面由30～80nm的纳米银颗粒组成。由于此种单质银微球独特的结构,可望在催化化学、生物化学、材料等诸多领域得到很好的应用。
The porous silver micro-spheres were prepared by using a template made of cationic exchange resin. The samples were characterized by SEM, EDS, XRD,XPS and UV-Vis. The result indicated that the hollow micro-sphere with 200～500μm in particle size has porous structure on the surface which consists of nanocrystals of 30～80 nm in size. For the porous and hollow structure of the silver micro-spheres, it can be expected to application in photocatalysis, biochemistry, and material etc. field.
