| Abstract | : | Synthesis of Graphene Oxide (GO) material with variations in permanganate/graphite ratio has been carried out. This research purposes to study the impact of increasing oxidizing agents to graphite on the chemical structure and properties of the GO material produced. All GOs were synthesized using the improved Tour method with three variations of permanganate/graphite ratios of 5, 6, and 7, which were subsequently mentioned as GO-5, GO-6, and GO-7. The results obtained include GO-5, GO-6, and GO-7, respectively having a d spacing value of 0.843; 0.891; 0.894 nm by XRD analysis and 0.768; 0.756; 0.772 nm by SAED analysis. Based on the FTIR data, all GO materials bring up the peak of oxygen-functionalized carbon absorption with strong intensity at wavenumbers of ~3400 for O-H, the weak intensity at ~2800 for C-H sp3 , the weak intensity at ~1700 for C=O, the medium intensity at ~1500 for C=C of aromatic carbon, the weak intensity of ~1300 for C-O-C of ether and ester, and weak intensity of ~1000 for C-OH for carboxylic acids and alcohols. TEM images of the three materials show a similar structure in the form of thin and transparent layers. The main peaks with the highest absorbance at the wavelength of 237?238; 235?238; 239?242 nm, meanwhile the band gap energy produced was 3.53; 3.71; 3.55 eV respectively for GO-5, GO-6, and GO-7. |
