Silver Nanoparticle Decorated on ZnO@SiO2 Nanocomposite and Application for Photocatalytic Dye Degradation of Methylene Blue

摘要

The synthesis was ZnO nanoparticle by hydrothermal method and composites with SiO2 nanoparticles (ZnO/SiO2). Ag NPs decorated on the impetus surface in substance decrease the strategy of ZnO/SiO2 nanocomposite on the catalyst surface in chemical reduction method. The catalyst was characterized by XRD, FE-SEM, EDAX, FT-IR and UV-visible spectroscopy. The photocatalytic performance of ZnO/SiO2 nanocomposite clearly indicated the enhancing of the catalytic activity under visible light with decorated Ag NPs. The Ag NPS improve the photocatalytic activity of MB dye degradation efficacy 81% of ZnO/SiO2-Ag.
