Synthesis of Graphene on Conducting Substrate by Electrochemical Deposition Method

Abstract

In this paper, detailed consideration for electrochemical fabrication and optimization of different components used in energy storage device. Fabricated electrode contained three layers: RGO, CNT, and RGO (RGO/CNT/RGO). GO nanosheets were electrochemically modified to RGO utilizing potential scanning from 0 to -1.5 V versus silver chloride electrode during electrodeposition. ITO coated glass and glassy carbon electrode has been utilized as substrate through this research investigation to understand the physical, morphological and structural characteristics of the fabricated electrode. AFM and FESEM were performed to identify morphological and structural properties of the fabricated electrodes components. Besides, electrochemical properties were studied by Cyclic Voltammetry which indicates electrode surface area enhanced due to incorporation of RGO and CNT. Accordingly, results show the fabricated electrodes could enhance performance of energy storage devices. Since unique surface area can boost mobility of electrons on top of surface there must be a good trade-off accessible among the electrical conductivity and the total ion transportation in structural pores.
