Full TextAbstract
Synthesis of silver nanoparticles by photochemical reduction of silver nitrate was carried out in water as an environmentally safe solvent using Preyssler acid, H14[NaP5W30O110], as the reaction promoter. Poly (N-vinyl-2-pyrolidone) (PVP) and formaldehyde were used as stabilizer and reductant agent, respectively. Our results have shown that UV irradiation increased the rate of reaction and decreased the size of synthesized silver nanoparticles. Metal nanoparticles were characterized by ultraviolet–visible (UV-Vis) spectroscopy, x-ray diffraction (XRD) and transmission electron microscopy (TEM). The catalytic performance of silver nanoparticles for photodegradation of methyl orange (MeO) as an azo dye model, has been investigated in aqueous solution. UV-Vis studies showed that Ag nanoparticles catalyzed photodegradation of this azo dye and the reaction rate was increased by the amount of catalyst.
