Abstract: A nanostructured composite electrode is provided that includes a pair of conductive metal foils and a multiplicity of ordered nanostructures formed on each conductive metal foil. The ordered nanostructures include functionalized carbon multi-walled nanotubes electrophoretically deposited onto the metal foils. The ordered nanostructures also include synthesized nanoparticles electrophoretically deposited onto each of the carbon multi-walled nanotubes and the metal foils in proportion to the concentration of the carbon multi-walled nanotubes while in a stable colloidal suspension with the synthesized nanoparticles during electrophoretic deposition.

Abstract: A method for preparing a nanostructured composite electrode through electrophoretic deposition and a product prepared thereby are presented. A conductive material and an active material are suspended into a stable suspension in solution by ultrasonication. The conductive material includes functionalized carbon multi-walled nanotubes. The active material includes synthesized nanoparticles. A surface charge is applied to the active material by adding an electrolyte into the stable suspension. At least two electrodes are introduced into the stable suspension in opposing parallel orientation. A direct current electrical field is formed between the electrodes sufficient to cause conductive material and the active material formation thereupon.
