Nanocomposites of Ag/ZnOnanorodswere prepared by a simple sonochemical method. The morphology and crystallinity of the nanocomposite were studied using SEM, AFM and X-Ray Diffractometer. XRD analysis shows a good crystalline property of both Ag nanoparticles and ZnO nanorods. Scanning electron microscopy (SEM) images of the Ag/ZnO films revealed the uniform distribution of Ag nanoparticles on ZnO nanorods. The effect of Ag on gas sensing properties was investigated. It was found that composite film provides good response to low concentrations of gases and shows excellent selectivity in the presence of interfering gases like NH3 and NO2 at room temperature.
