The structure shape of the produced Ag hollow rods was deduced by X-ray diffracxtion (XRD) and scanning electron microscopy (SEM). X-ray diffraction was used to examine the structure of Ag-particles with average crystallite size 25.4 nm. Lattice strain and dislocation density were also calculated. In this study we focus on the synthesis and the structure properties of the produced Ag metals with differet structures have various potential applications such as conductors, catalysts and chemical sensors.
