Abstract
In this research, silver nanoparticles (AgNPs) were intercalated between layers of nano-metal oxides zinc oxide nanoparticles (ZnONPs) by chemical methods (sol-gel method). The AgNPs were first prepared by chemical methods using glucose solution as a reducing agent to convert AgNO3 into AgNPs, and then they were intercalated between layers of ZnONPs. AgNPs were identified using visible spectrophotometry the highest wavelength value was 490 nm. The ZnONPs, AgNPs and Ag-ZnONPs compund were also identified using several techniques, including X-ray diffraction, FT-IR spectroscopy, AFM and SEM. The X-ray diffraction of the Ag-ZnOPNs compound indicates the presence of Ag metal on the surface of zinc oxide. While Scanning Electron Microscope examinations showed that the average particle size in Ag-ZnOPNs compund was 90nm, while the average particle size of AgNPs was 86nm, and the average size of pure ZnONPs was 89nm. While the Atomic Force Microscope technique revealed the three-dimensional image of the prepared compounds, the AgPNs aggregates had heights ranging from (0.00-5.41) nanometers, while the ZnOPNs aggregates had heights ranging from (-0.03-2.04) nanometers, while the molecular aggregates of the Ag-ZnOPNs compound rang (-0.09-4.99) nm. The release kinetics of AgPNs between ZnOPNs layers was studied it was the pseudo-second order model, and fiend percentage of release AgPNs within half an hour was approximately (99%) at pH 10.
