Hybrid supercapacitors were fabricated with both pristine and H2Ti12-xZnxO25-x (x = 0.15, 0.3, 0.45, 0.6) anode electrodes. The structural properties and morphology of particles after zinc doping were confirmed by X-ray diffraction (XRD), Rietveld refinement, X-ray photoelectron spectroscopy (XPS), and scanning electron micron microscopy (SEM). The electrochemical performances of the hybrid supercapacitors were measured. The results show that the H2Ti11.7Zn0.3O24.7 not only enhanced discharge specific capacitances of 70.7 Fg (1) at 0.5 Ag (1), but also capacitance retention of 92% after 1000 cycles. In addition, H2Ti11.7Zn0.3O24.7 has lower polarization and charge transfer resistance (R-ct) of 0.142 Omega. The power densities and energy densities of H2Ti11.7Zn0.3O24.7 were 42.4-8.1 Wh kg (1) and 182-5676.2 W kg (1) at 0.1 and 3 Ag (1), respectively. Consequentially, Zn doping improved structure stability and electrochemical performance of H2Ti12O25. Therefore, hybrid supercapacitors were fabricated using a H2Ti11.7Zn0.3O24.7 anode can be regarded as energy storage devices. (C) 2017 Elsevier Ltd. All rights reserved.
