The use of metallic electrodes both from noble (Au, Pt, Pd) and active metals (Fe, Ni, Cu, Al etc.) as platforms for the electrochemical synthesis of nanostructurized polyaniline (PAn) is an actual problem for nanochemistry of electrically conductive polymers [1]. Such nanostructurized with nanofibrilic morphology polyanilines serve as platforms for the chemical or electrochemical reduction of the metals from their salts solutions and as the electrically conductive matrix-carriers of the formed metal nanoparticles, that determines their use as electrocatalytic systems. The synthesis of nanorods PAn structures is much more complex and requires the use of different types of templates, for example specially grown aluminum oxide layer on the Al surface. However, such method of the synthesis of nanostructurized PAn is multistage, too time consuming, and highly costly. Therefore, the use of unprepared aluminum electrode (coated with a natural oxide layer) can be very interest and perspective alternative method of the production of PAn nanorods.
