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 in situ carbon-supported titanium oxide (ICS-TiO 2 ) electrode has been prepared using sucrose and TiO 2 powder. The ICS-TiO 2 powder was prepared by slipcasting, followed by the annealing of the TiO 2 slurry. Sucrose was added to the TiO 2 slurry as a soluble carbon source, and was converted into carbon at 600 C then coated on the TiO 2 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 2 demonstrated that this material exhibits an efficient value of specific capacitance (277.72 F g À1 at 25 mV s À1 ) for charge storage. ISC-TiO 2 also exhibits a specific capacitance of 180 F g À1 at 2 A g À1 in a 1 M Na 2 SO 4 aqueous electrolyte. The results suggest that ICS-TiO 2 can be utilized as a highperformance electrode material for supercapacitors with desirable electrochemical properties.

This study presents a fabrication and electrochemical properties of nickel ferrite/graphene nanocomposite as electrodes material for supercapacitor application. The as-prepared electrode was characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and Xray photoelectron spectroscopy. The electrochemical properties were measured using cyclic voltammetry, galvanostatic charging/discharging methods and electrochemical impedance spectroscopy. Graphene nanosheets play an important role of governing the morphology of the electrode material and thereby enhancing the electrochemical performance of the composite electrode. The specific capacitance of 207 F/g is obtained for nickel ferrite/graphene nanocomposite, which is almost 4 times larger than pure nickel ferrite. The nanocomposite showed a stable capacitance of 95% after 1000 cycles in 1 M Na 2 SO 4 electrolyte. Electrochemical impedance spectroscopy results indicate that graphene nanosheets reduced the charge transfer resistance on the composite electrode. The obtained results show that the nanocomposite has a great potential to be used in supercapacitor with good electrochemical performance and longer cycle stability.

Nanocomposite material proves to be the best candidate to match today's technological need as fascinating properties can be achieved by combining two or more nanomaterials. Among various nanomaterials, graphene is able to stand out far ahead of all others because of its novel structure and exclusive characteristics. In particular, graphene-metal nanocomposites have attracted enormous interest for their prospective use in various fields, including electronics, electrical and energy-related areas. However, for the utmost use of potential of graphene, it has to be homogenously embedded into metal matrices. Thus, appropriate synthesis route is decisive to obtain graphene-metal nanocomposites with desired properties. This chapter will summarize the different synthesis routes of high-quality graphene-metal nanocomposites along with their current developments. one is the called matrix or binder which encloses and binds together fragments or fibres of the other material, termed as reinforcement. If one of the constituent materials of the composite is of nanometer dimension then the composite is called nanocomposite 1 and in most of the cases the nanomaterial are used as reinforcement material. Since the advent of nanomaterial several of them is used to synthesise nanocomposite, as nanomaterial possesses remarkable improvement in their properties compared to their bulk counterpart 2 . The inclusion of nanomaterial as the reinforcement in the parent matrix also significantly enhances the properties of the resulting nanocomposite 3 . Among the different nanomaterials graphene has emerged as one of the most prospective nanomaterials due to the unique combination of its exotic properties 4 . Based on the binder material graphene nanocomposite can be categorized as graphene metal/metal oxide nanocomposite 5 , graphene ceramic nanocomposite 6 , graphene semiconductor nanocomposite 7 and graphene polymer nanocomposite 8 . Among various nanocomposites, graphene-metal/metal oxide composites have attracted considerable attention because of their potential applications in energy 9 and health 10 -related areas.
