XRD patterns of GO and EGFP-rGO. In the XRD pattern of GO (top panel), the strong and sharp peak at 2θ = 11.7°c corresponds to an interlayer distance of 7.6Å. EGFP-rGO (bottom panel) has a broad peak centered at 2θ = 25.8°, which corresponds to an interlayer distance of 3.6Å. These XRD results are related to the reduction of GO by EGFP and the process of removing intercalated water molecules and oxide groups. At least three independent experiments were performed for each sample and reproducible results were obtained. Data from a representative experiment are shown.
