Electrochemical synthesis of silver nanoparticles in poly(vinyl alcohol) solution
In this work silver/poly(vinyl alcohol), Ag/PVA, colloid dispersions were obtained by electrochemical reduction of Ag+ ions. The electrochemical synthesis of silver nanoparticles in the aqueous solutions of 5 and 10 wt. % PVA, containing 0.1 M KNO3 and 3.9 mM AgNO3, was performed at constant current...

Summary: | In this work silver/poly(vinyl alcohol), Ag/PVA, colloid dispersions were
obtained by electrochemical reduction of Ag+ ions. The electrochemical
synthesis of silver nanoparticles in the aqueous solutions of 5 and 10 wt. %
PVA, containing 0.1 M KNO3 and 3.9 mM AgNO3, was performed at constant
current density of 25 mA cm-2, and during synthesis time of 10 min. The
presence of silver nanoparticles was confirmed by UV-vis spectroscopy. Cyclic
voltammetry analysis and FTIR spectroscopy indicated the interactions between
silver nanoparticles and PVA molecules. TEM analysis confirmed spherical
shape of the obtained silver nanoparticles, with the mean diameter of 15 ? 9
nm. |
