Abstract
Nanoporous anodized tin oxide films have many potential applications in the fields of photocatalysis, sensors and electrode materials. In this paper, we found that potential played a dominant role in the morphological evolution of anodized tin oxide films in electrolyte containing F− and S2−. The critical potential for the formation of nanoporous structure was determined. Porous anodized tin oxide films with different nanostructure can be prepared by the application of low anodization potential and high anodization potential. The I–V curve analysis showed that the change of the nanoporous of tin oxide films at different potentials could be attributed to the oxygen which generated by the electronic current. The valence regulation of Sn element in anodized tin oxide film can be achieved by controlling the potential.
