Responsive UV-light Photocatalytic of Ag/ZnO Nanocomposites for Removal of Brilliant Blue Dye: As a Model for Advanced Chemical Studies

Today’s nanocomposites with strong photocatalytic degradation are used for removal of pollutants. A low-cost method for creating materials with zinc oxide nanostructures intended to be employed in the treatment of water contaminated by artificial organic pollutants such as vivid blue dye. Nanoparticles were made using a hydrothermal process at ۱۶۰ °C, and an ultraviolet photodeposition technique was subsequently used to create an Ag/ZnO nanocomposite. The products were described using transmission electron microscopy (TEM), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). Using ultraviolet (UV) light and Ag-ZnO, the photo dissociation of brilliant blue (BB) dye was investigated. The effect of several parameters, including calcination temperature, dye concentration, surface mass and incident light intensity, were examined. The ultimate findings show that the zinc oxide surface's crushing efficiency, which calcination at ۵۰۰ °C, produces the best outcomes. The effects of absorbent BB dye on the mass dosage of ۰.۳ g and the improved elimination percentage after ۱ h. The absorption efficiency changed from ۹۹.۸۷ % to ۷۲.۵۵ % when the concentration of BB dye was increased from ۱۰ to ۵۰ mg/L and the increase in (Ag/ZnO) NPs from ۰.۰۵ g to ۰.۴ g, the photocatalytic efficiency increased from ۴۹.۵۵۴ % to ۹۷.۴۰۲ %. In addition, it was demonstrated that when brilliant green dye concentration decreases, the rate of photocatalytic breakdown increases. The rate of photocatalytic breakdown increased as the light's intensity increased.
