Templated synthesis of honeycomb-like TiO2 for supercapacitor applications

A facile and cost-effective procedure to synthesize honeycomb-like porous TiO, which exhibits specific capacitance of 0.2 F/cm at 20 mV/s, was proposed. Scanning Electron Microscopy (SEM), thermogravimetric analysis (TG), UV/Vis, Fourier Transform Infrared Spectroscopy (FTIR), and X-ray diffraction (XRD) were employed for characterization. The electrochemical performances of the electrode were investigated in acidic solution.
