Degradation of Titan Yellow Using ZnO/Ag Embedded with Fe_3O_4 Nanoparticles under Visible Light-Induced

摘要

The Fe_3O_4/ZnO/Ag nanocomposite has been successfully synthesized, and the material was applied as a photocatalyst to degrade titan yellow. The Fe_3O_4 was synthesized through sono-coprecipitation method using NH_4OH as a precipitating agent. The synthesized ZnO/Ag was performed via coprecipitation method using ethylene glycol, zinc acetate, and silver nitrate as a reagent. This study investigated several parameters, such as the effect of time reaction, equilibrium state, and material responsiveness under visible light irradiation. The XRD measurement indicated the presence of ZnO, Ag, and Fe_3O_4, whereas the TEM image displayed the photocatalyst had a nanosized particle with approximately 17 nm. The photocatalyst activity has shown the equilibrium process at 60 minutes. The highest degradation (up to 90%) of titan yellow was achieved by Fe_3O_4/ZnO/Ag nanocomposite. The reusability test showed that Fe_3O_4/ZnO/Ag nanocomposite had high stability and could be used up to three times.
