Sonochemical Synthesis and Characterization of Ag/ZnO Heterostructure Nanocomposites and their Photocatalytic Efficiencies

Ag/ZnO heterostructure nanocomposites containing different amounts of Ag were successfully synthesized in surfactant-free solutions by a sonochemical deposition. The samples were characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy. The results show that all heterostructure...
