carbon-supported titanium dioxide (ICS-TiO) as an electrode material for high performance supercapacitors.

Supercapacitors have attracted significant attention in the last few years as they have the capability to fulfill the demand for both power and energy density in many energy storage applications. In this study, an carbon-supported titanium oxide (ICS-TiO) electrode has been prepared using sucrose and TiO powder. The ICS-TiO powder was prepared by slipcasting, followed by the annealing of the TiO slurry. Sucrose was added to the TiO slurry as a soluble carbon source, and was converted into carbon at 600 °C then coated on the TiO particles. The morphological and structural evolution of the electrode was investigated by FEG-SEM, FEG-TEM, XRD, BET, FTIR, XPS and Raman spectroscopy. The electrochemical characterization of ICS-TiO demonstrated that this material exhibits an efficient value of specific capacitance (277.72 F g at 25 mV s) for charge storage. ISC-TiO also exhibits a specific capacitance of 180 F g at 2 A g in a 1 M NaSO aqueous electrolyte. The results suggest that ICS-TiO can be utilized as a high-performance electrode material for supercapacitors with desirable electrochemical properties.
