【 摘 要 】

The present exploration emphasizes on the fabrication of graphene sheets with optimum hydroxy (-OH) functionalities which would establish tuned electrical charge storage capacity thereby revealing appreciable electrochemical signature. Compared to other available chemical procedures, here we have adopted a simple, facile-one-pot sonochemical route for the synthesis of the material: Hydroxy-Functionalized Graphene (hG), starting from pristine graphite powder. The as-synthesized sample was characterized using FTIR, XPS, TGA and FESEM techniques which prompted formation of hydroxyl-functionalized graphene. We further investigated the electrochemical performances using techniques such as cyclic voltammetry and chrono-potentiometric charging/discharging cycles. The material shows potential applications in energy storage devices.
