Synthesis of Nano-Ag particles using Sodium Borohydride
These particles were synthesized by the chemical reduction method of AgNO3 using NaBH4. The borohydride anions were adsorbed onto silver nanoparticles and addition of PVP prevented the aggregation of particles. UV–vis absorption spectra, dynamic light scattering (DLS) and transmission electron micro...

| description | These particles were synthesized by the chemical reduction method of AgNO3 using NaBH4. The borohydride anions were adsorbed onto silver nanoparticles and addition of PVP prevented the aggregation of particles. UV–vis absorption spectra, dynamic light scattering (DLS) and transmission electron microscopy (TEM) have been used to trace the growth process and elucidate the structure of the silver nanoparticles. A solution in its UV–Vis absorption spectrum showed surface plasmon resonance absorption bands about 420 nm. We obtain silver colloids of average size 47 nm with a standard deviation of 15 nm after separation and washing procedures. |
