Effect of synthesis route on the morphologies of silver nanostructures by galvanic displacement reaction

Abstract The present study is concerned with the preparation of Ag nanostructures by reduction of AgNO 3 with zinc foil by galvanic displacement reaction. The results confirm that the synthesis route has a direct influence on the morphologies of Ag nanostructures. In addition, the effect of synthesis conditions, including the concentration of AgNO 3 aqueous solutions and reaction time, are investigated. X-ray diffraction (XRD), filed emission scanning electron microscope (SEM) and UV-vis spectra are used to characterize the obtained products. A reasonable formation process of Ag nanostructures is proposed based on the characterization results.
