Nanocomposites structures based on the electrochemical assembling of zinc oxide nanorods and carbon nanotubes

We report two electrochemical routes to obtain composites structures at nanometric scale with zinc oxide nanorods (ZnO NRs) and carbon nanotubes (CNTs). The first route is based in the electroprecipitation of ZnO NRs with CNTs dispersed in the electrolyte on ITO electrodes while the second one is based on the electroprecipitation of ZnO NRs on CNTs paper electrodes. CNTs paper has been obtained by pressing CNTs, which then can acts as a pure working electrode. The results obtained are preliminary discussed taking into account the electroprecipitation phenomenon assisted by hydrodynamic regime and the electrical contact between ZnO NRs and CNTs and electron transfer kinetic.
