Abstract

This work consists of the project of scientific initiation that aims at the development, assembly and characterization of electrodes of reduced graphene oxide (OGR) in electrolytic medium composed of ionic liquids. The proposed project will be directly linked to the thematic project FAPESP 2015 / 26308-7 "Optimization of the physico-chemical properties of nano-structured materials and their applications in molecular recognition, catalysis and energy conversion / storage" and the post-doctoral project FAPESP 2017 / 11784-3 "Study of hybrid materials in the development of devices for organic electronics and energy storage". For this, the synthesis of the reduced graphene oxide, from graphite, will be explored and this will be characterized via RAMAN, FTIR, Impedance Spectroscopy and Scanning Electron Microscopy. The physicochemical properties of ionic liquids by ion exchange will also be studied. As a sequence will be made the construction of the electrode and the study of its electrochemical behavior. In this way, it is intended to understand the operation of the electromagnetic material OGR in varied electrolytic media. (AU)
