Abstract
Carbon-based material is an alternative material that has the potential for electronic application such as dye sensitized solar cells (DSSC). Reduced graphene oxide (rGO) is one of carbon-based materials. rGO has corrosion resistance, good electrical conductivity, environmentally friendly, and inexpensive for various electronic devices. In this report, rGO was synthesized from graphite using sonication-oxidation method. rGO was prepared by sonicating-oxidizing graphite to form graphite oxide. rGO was characterized by FTIR and Raman spectroscopy, XRD, SEM and TEM. The Raman spectrum shows typical D-band, G-band, and 2D-band peaks present in graphite, rGO and graphene oxide (GO). The XRD spectrum of rGO shows a shift towards which is smaller than the graphite peaks, besides that the rGO peaks are wider than the graphite peaks. The SEM image shows the morphology of rGO in the form of thin and wide nano-sheets. While the rGO TEM profile shows a thin transparent layer.
