Electrodeposition of Metals and Their Oxides on Electrochemically Modified Three-Dimensional Carbon Nanotubes

The change in the qualitative and quantitative composition of oxygen-containing surface groups on the fibers of carbon-fibrous and nanocarbon materials is studied as a result of their electrochemical modification in solutions of indifferent electrolytes. The effect of preliminary electrode treatment on the efficiency of electrodeposition of metals on carbon-fibrous and nanocarbon materials is shown by the example of electrodeposition of cadmium, copper, nickel, and platinum, and that of metal oxides by the example of precipitation of manganese oxide. Preliminary electrochemical treatment of these carbon materials allows obtaining precipitates in the form of nanosized particles and in the form of continuous coating with good adhesion to the surface of the fibers of carbon materials.
