There are various methods for synthesizing SnO2-Ag2O nanocomposite such as chemical vapor deposition, coprecipitation, spray-pyrolysis, sol-gel, laser ablation, hydrothermal routes, and so on. In this study, SnO2-Ag2O nanocomposite powders have been synthesized by sol-gel method using NH3OH/NaOH route. The obtained powders were characterized by scanning electron microscopy, X-ray Diffraction, X-ray fluorescence, and Fourier transform infrared spectroscopy. Monodispersed SnO2-Ag2O nanosized composite ranging from 80 to 400nm in size in the NH3OH/NaOH route was obtained when the gel was heat-treated at different temperatures. Finally, it was found that optimum uniform distribution of the silver in SnO2 could be achived at an annealing temperature of 400 degrees C.
