Zn-doped titanate nanowires (TNWs) with the chemical formula of ZnxTi3-xO7 (Na0.96 H1.04 × 3.42H2O) where x = 0, 0.05, 0.1, 0.2, and 0.3 were synthesized by a hydrothermal method at a temperature of 130 °C for 24 h. The synthesized samples were characterized by scanning electron microscope (SEM), X-ray diffraction (XRD), and Brunauer-Emmett-Teller (BET) techniques. It was found that, the diameter and length of the nanotubes were in scale of nanometer. Electrochemical properties of prepared samples were investigated by cyclic voltammetry (CV), galvanostatic charge - discharge (GCD) and electrochemical impedance spectra (EIS) methods. The specific capacitance of 23 F g-1 (at 1 mV s-1) was observed for Zn-doped TNWs.
