Chemical Synthesis and Charactrization of Graphene Oxide Nanosheets

Graphene oxide (GO) has recently grabbed attention due to its potential to be used as a precursor forgraphene synthesis. In this work, the GO nanosheets were prepared by a chemical exfoliation technique called modifiedHummes method. The structural and chemical properties of the GO nanosheets were characterized by cyclicvoltammetry, XRD, FT-IR, Raman spectroscopy and scanning electron microscopy (SEM). The FT-IR resultsconfirmed the existence of oxygen-containing groups on the GO nanosheets and the Raman spectra of GO nanosheetsshowed the presence of defects on the surface of nanosheets. These results indicate that the GO nanosheets could beused as a material for graphen synthesis by chemical or electrochemical reduction and a promising material forsynthesis of graphene-nanoparticle composites
