Abstract

The electrochemical properties of graphene can be significantly enhanced due to the incorporating of hetero-atoms into the graphene. In this article Crumpled-like TiO2–Pt/graphene nanocomposite from graphene oxide (GO), titanium (III) chloride (TiCl3) and Hydrogen hexa chloro palatinate (H2PtCl6) was synthesized via a simple reflux strategy and employed as a simple capacitor electrode material. The nanocomposite was characterized by XRD, XPS, FESEM, HRTEM and the electrochemical properties were investigated by cyclic voltammetry (CV). Electrochemical characterization for introduced nanocomposite indicated that the corresponding specific capacitance is 160 F/g (at 5 mV/s) with good stability. The high electrochemical performance is recognized to the presence of Pt nanoparticles on the nanocomposite and graphene distinct characteristics. To the best of our knowledge this is the first report on TiO2–Pt/graphene nanocomposite as an electrical double layer capacitor material.
