YANEZ, Javier E. Rodríguez. Characteristics of the spontaneous deposition of Sn in polycrystalline Pt. Port. Electrochim. Acta [online]. 2012, vol.30, n.2, pp.111-120. ISSN 0872-1904.  https://doi.org/10.4152/pea.201202111.

Spontaneous deposition of tin (Sn) in polycrystalline platinum (Pt pc) from a sulfuric acid solution of tin salts, was evaluated by conventional electrochemical techniques, to determine its characteristics. Tin was deposited from a solution of SnCl2 or SnSO4 in sulfuric acid 1 M. The degree of surface coating by Sn was calculated by evaluating the region of hydrogen electrosorption through voltammograms performed using solutions containing only the supporting electrolyte, and the supporting electrolyte containing the Sn salt, respectively. The adsorption behavior of tin and oxidation have been studied by the results obtained with platinum electrodes and electrodes of platinum/tin, considering as comparative parameter the adsorption efficiency with respect to the area free of platinum.

Palavras-chave : tin; platinum; spontaneous; electrocatalysis; voltammetry.
