Morphological and Structural Characterization of Tin Dendritic Nanostructures Produced by Various Electrodeposition Processes

Abstract

In this study, Sn powders were electrodeposited from an alkaline electrolyte containing 20 g/l SnCl2 × 2H2O in 250 g/l NaOH at the room temperature by application of both potentiostatic and galvanostatic regimes of the electrolysis. Electrodeposition was performed at various cathodic potentials (−1185, – 1200, −1270, – 1400, – 1600 and – 1800 mV vs. Ag/AgCl), and at a current density outside the plateau of the limiting diffusion current density (−3.0 mA cm-2). Morphology of Sn particles is characterized by scanning electron microscope (SEM) and crystal structure by X-ray diffraction (XRD).
