|Title:||Characterization of nanocrystalline Ag/SiO2 nanocomposites and synthesis by wet chemical method|
|Keywords:||Silver nitrate;Doping effect;Sol-gel;Nanocomposites|
|Abstract:||The silver/silica nanocomposites have been successfully prepared by the sol-gel process. After drying in air at 70°C for 30 min, samples are heat treated in air at 150, 300 and 500°C. Characterizations have been made by ultraviolet-visible (UV-VIS-NIR), X-ray diffraction (XRD), Differential scanning calorimetry (DSC), Fourier transform infrared spectroscopy (FTIR) and Scanning electron microscopy (SEM). Mechanisms of silver clusters formation in the densified silica matrix with respect to thermal treatment have been studied|
