Abstract
The development of methodologies for the fabrication of nanostructured materials that provide control over their microstructural features and composition represents a fundamental step in the advancement of technologies for the production of materials with well-defined functional properties. The top-down electrochemical approach of pulse electrolysis has been demonstrated as a viable method for producing nanostructured materials, with particular efficacy observed in the synthesis of tin oxides. This method allows for significant control over the composition and shape of the resulting SnOx particles by modifying the anionic composition of the aqueous electrolyte, obviating the need for additional capping agents in the synthesis process and eliminating the requirement for high-temperature post-treatment. The composition and microstructural characteristics of these oxides are contingent upon the differing stability of tin fluoride and chloride complexes, as well as the distinct mechanisms of interaction between chloride and fluoride anions with an oxidized tin surface, which is influenced by the varying kosmotropic/chaotropic nature of these anions. The composition and microstructural characteristics of the obtained dispersed tin oxides thus determined their potential applications as an anode material for lithium-ion batteries, as a photocatalyst, or as an oxyphilic component of a hybrid support for a Pt-containing electrocatalyst.
