Abstract:Stable silver nanoparticles were successfully synthesized in the presence of sodium alginate,which were reduced by NaBH4.The silver nanoparticles were characterized by UV-vis spectroscopy,X-ray diffraction(XRD)and transmission electron microscopy(TEM).The results indicate that the sizes of the silver nanoparticls thus obtained were in the range of 10~35 nm.Moreover,the Ag nanoparticle dispersion prepared via this method is stable for over three months at room temperature.
Keywords:silver nanparticle  sodium alginate  X-ray diffraction  transmission electron microscope
