             abstract = "A direct and quick approach to performer rGO (reduced graphene 
                         oxide) and TiO2 (titanium oxide) depositions using electrochemical 
                         techniques to reduceGOon CF substrate (rGO/CF) with subsequent 
                         TiO2 nanoparticles electrodeposition to produce ternary 
                         nanocomposites TiO2/rGO/CF is presented. Anew bath solution 
                         consisting of titanium chloride, H2O2 and supporting salt LiClO4 
                         was develop in order to simplify and reduce the preparation time 
                         of TiO2 synthesis. Scanning electron microscopy images showed 
                         irregular and flakes-like shape aggregates with high particle 
                         density on CF substrate characteristic of rGO morphology. 
                         Homogeneous distribution of TiO2 nanoparticles on TiO2/rGO/CF 
                         surfaces were observed on graphene sheets without modifying their 
                         morphologies. TheCVcurves presented a quasi-rectangular shape, 
                         indicating that the charge storage occurs preferentially through 
                         of the TiO2/rGO/CF electric double layer. Galvanostatic tests 
                         showed the highest time of the charge/discharge for TiO2/rGO/CF_5 
                         sample, probably attributed to its surface area increase, 
                         improving its charge storage capacity. These results assured that 
                         TiO2/rGO/CF ternary composite has great potential as new electrode 
                         for supercapacitor application.",
