Electrochemical Template Synthesis of Copper Nanotubes from Nitrate and Sulfate Electrolytes

Resumo

A comparative study of the crystal structure of the ordered arrays of copper nanostructures prepared by the electrochemical synthesis method in polymer templates from solutions of nitrate and sulfate electrolytes was made. Changes in the phase composition, unit cell parameter, degree of crystallinity, and crystallite size depending on the electrolyte composition and synthesis conditions were investigated. It was shown that the addition of 10 g/L of ethanol as a surfactant to both the sulfate and nitrate electrolytes allows preparing monocomponent copper nanotubes with high degrees of crystallinity.
