X-ray diffraction and X-ray photoelectron spectroscopy confirm the existence of MoO_3-<i>x</i> . The MoO_3-<i>x</i> /TiO₂ electrode prepared at 550 °C exhibits a high specific capacitance of 23.69 mF cm^-2 at a scan rate of 10 mV s^-1 and good cycling stability with capacitance retention of 86.6% after 1000 cycles in 1 M Na₂SO₄ aqueous solution.
