In this study, silver (Ag) doped zinc oxide (ZnO) nanoparticles were synthesized using different precursors and characterized for various properties. These nanoparticles were found to be effective photocatalysts for the degradation of methylene blue and rose bengal dyes under visible light. Furthermore, the antifungal activity of Ag doped ZnO nanoparticles against Bipolaris sorokiniana was also investigated.
In this work, silver (Ag) doped zinc oxide (ZnO) nanoparticles were synthesized using zinc chloride, zinc nitrate, and zinc acetate precursors with (0 to 10) wt % Ag doping by a simple reflux chemical method. The nanoparticles were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, ultraviolet visible spectroscopy, and photoluminescence spectroscopy. The nanoparticles are studied as a photocatalyst for visible light driven annihilation of methylene blue and rose bengal dyes. The 5 wt % Ag doped ZnO displayed optimum photocatalytic activity toward methylene blue and rose bengal dye degradation at the rate of 13 x 10-2 min-1 and 10 x 10-2 min-1, respectively. Here we report antifungal activity for the first time using Ag doped ZnO nanoparticles against Bipolaris sorokiniana, displaying 45% efficiency for 7 wt % Ag doped ZnO.
